	+ -	Show Abstract Domain ontology is a descriptive representation of any particular domain which in detail describes the concepts in a domain, the relationships among those concepts and organizes them in a hierarchal manner. It is also defined as a structure of knowledge, used as a means of knowledge sharing to the community. An Important aspect of using ontologies is to make information retrieval more accurate and efficient. Thousands of domain ontologies from all around the world are available online on ontology repositories. Ontology repositories like SWOOGLE currently have over 1000 ontologies covering a wide range of domains. It was found that up to date there was no ontology available covering the domain of "Sufism". This unavailability of "Sufism" domain ontology became a motivation factor for this research. This research came up with a working "Sufism" domain ontology as well a framework, design of the proposed framework focuses on the resolution to problems which were experienced while creating the "Sufism" ontology. The development and working of the "Sufism" domain ontology are covered in detail in this research. The word "Sufism" is a term which refers to Islamic mysticism. One of the reasons to choose "Sufism" for ontology creation is its global curiosity. This research has also managed to create some individuals which inherit the concepts from the "Sufism" ontology. The creation of individuals helps to demonstrate the efficient and precise retrieval of data from the "Sufism" domain ontology. The experiment of creating the "Sufism" domain ontology was carried out on a tool called Protȳgȳ. Protȳgȳ is a tool which is used for ontology creation, editing and it is open source.

Select this Article		Call-graph-based inter-class MM path generation Wei He and Ruilian Zhao Proc. SPIE 8349, 834905 (2011); http://dx.doi.org/10.1117/12.920088 Online Publication Date: Jan 11, 2012 Full Text: \| Download PDF
	+ -	Show Abstract Inter-class testing is the testing of classes for composing an object-oriented system or subsystem during integration. MM Path is defined as an interleaved sequence of method executions linked by messages. It represents the interactions between methods in object-oriented software well, hence fits for object-oriented integration testing. However, the current MM Path generation methods only support intra-class testing. In this paper, a call-graph-based approach is proposed to promote MM Path automatic generation from intra-class to inter-class level. The approach is evaluated by controlled experiments on 12 Java benchmark programs with two typical call graph construction algorithms, Class Hierarchy Analysis and Anderson's Points-to Analysis. Then, the impact of the two algorithms on inter-class MM path generation efficiency is studied. The result shows that our approach is practicable and Anderson's Points-to Analysis outperforms Class Hierarchy Analysis for inter-class MM Path generation.

Select this Article		A novel duplicate images detection method based on PLSA model Xiaofeng Liao, Yongji Wang, Liping Ding, and Jian Gu Proc. SPIE 8349, 834909 (2011); http://dx.doi.org/10.1117/12.920153 Online Publication Date: Jan 11, 2012 Full Text: \| Download PDF
	+ -	Show Abstract Web image search results usually contain duplicate copies. This paper considers the problem of detecting and clustering duplicate images contained in web image search results. Detecting and clustering the duplicate images together facilitates users' viewing. A novel method is presented in this paper to detect and cluster duplicate images by measuring similarity between their topics. More specifically, images are viewed as documents consisting of visual words formed by vector quantizing the affine invariant visual features. Then a statistical model widely used in text domain, the PLSA(Probabilistic Latent Semantic Analysis) model, is utilized to map images into a probabilistic latent semantic space. Because the main content remains unchanged despite small digital alteration, duplicate images will be close to each other in the derived semantic space. Based on this, a simple clustering process can successfully detect duplicate images and cluster them together. Comparing to those methods based on comparison between hash value of visual words, this method is more robust to the visual feature level alteration posed on the images. Experiments demonstrates the effectiveness of this method.

Select this Article		Image denoising by block-matching and 1D filtering Yingkun Hou, Tao Chen, Deyun Yang, Lili Zhu, and Hongxiang Yang Proc. SPIE 8349, 83490A (2011); http://dx.doi.org/10.1117/12.920202 Online Publication Date: Jan 11, 2012 Full Text: \| Download PDF
	+ -	Show Abstract In this paper, we develop a new image denoising method based on block-matching and transform-domain filtering. The developed method is derived from the current state-of-the-art denoising method (BM3D). We separate the 3D transform in the original method to two steps 1D transform, to further enhance the sparsity for signals whose elements are highly similar and to weaken the sparsity for those signals whose elements are dissimilar. Because the 1D filtering is on highly similar elements and the 2D filtering on image blocks are all removed, the image details can be better reserved and fewer artifacts are introduced than original method. Experimental results demonstrate that the developed method is competitive and better than some of the current state-of-the-art denoising methods in terms of peak signal-to-noise ratio, structural similarity, and subjective visual quality.

Select this Article		A novel multi-level segmentation method on oil spill of SAR image Yue Guo and XiaoFeng Wang Proc. SPIE 8349, 83490B (2011); http://dx.doi.org/10.1117/12.920203 Online Publication Date: Jan 13, 2012 Full Text: \| Download PDF
	+ -	Show Abstract Using SAR to monitor oil spill is a useful method. As the performance of oil spill on SAR images is similar with other oceanic phenomenon, it is difficult to distinguish between oil spill and "look-alikes". This paper presents a novel multi- level method to extract the oil film from original SAR image. The method can retain original edge information of oil film while separated it from the background. This paper applied lee filter, fuzzy c means, coherence filter and morphological operations to de-noise and segment SAR image. Experimental results show that the method can not only distinguish oil film and the sea, but revert part of edge information lost in the process of de-noising and the segmentation.

	+ -	Show Abstract Aimed projective distortion caused by tilted camera in traditional photogrammetry, a projective distortion self-corrected photogrammetry is proposed used to measure the projectile coordinates. The causes of projective distortion and the impact on the measurement accuracy are analyzed. Through the analysis of the imaging model of random points on the target, The formula to solve the object distance is deduced. The correspondence between the coordinates on the image and the coordinate on the target of the projectiles is established. According to Extraction and calculation of 4 markers sited on the target, the constant in the correspondence is solved. The measurement error caused by projective distortion is overcome. The absolute measurement of projectile coordinate on the target is realized. The test result shows that the projectile coordinate on the target can be accurately measured using the method designed in this paper. The accuracy and consistency of fire intensity measuring is increased. It also can be used to check the other related automatic measuring equipments.

	+ -	Show Abstract An image registration method is proposed in this paper for accurately aligning two images of the same scene captured simultaneously by visible CCD and IR (infrared) cameras. In image fusion systems, CCD and IR sensors are physically aligned as closely as possible and yet significant image mis-alignment remains due to differences in field of view, lens distortion and other camera characteristics. So, affine transformation is considered for aligning two images. At first, the corresponding feature point pairs are selected manually and that are used to calculate transform coefficients. Then, the value of the transform coefficients are optimized further by MI (mutual information) in global image. After the unregistered image is transformed by optimal transform coefficients, the accurately registered image can be obtained. The experimental results demonstrate that this method can provide highly accurate registered images for image fusion.

	+ -	Show Abstract Super-resolution image reconstruction aims to obtain a high-resolution image from multiple low-resolution images to get a better visual effect. It is widely used in many applications such as video surveillance, image recognition. This paper proposes a POCS super-resolution image reconstruction algorithm based on the projection residue to improve the visual effect of reconstructed HR image. The characteristic of this method is that it takes full advantage of the statistical property of projection residue included in the constraints and changes the modified threshold adaptively. The cause of the projection residue is analyzed and its characteristic parameter is calculated to restrain the solution. Experimental results show that our algorithm is effective in visual evaluation, and the PSNR is improved.

	+ -	Show Abstract Using optical sensor array, a precision motion control system in a conveyer follows the irregular shaped leather sheet to measure its surface area. In operation, irregular shaped leather sheet passes on conveyer belt and optical sensor array detects the leather sheet edge. In this way outside curvature of the leather sheet is detected and is then feed to the controller to measure its approximate area. Such system can measure irregular shapes, by neglecting rounded corners, ellipses etc. To minimize the error in calculating surface area of irregular curve to the above mentioned system, the motion control system only requires the footprint of the optical sensor to be small and the distance between the sensors is to be minimized. In the proposed technique surface area measurement of irregular shaped leather sheet is done by defining velocity and detecting position of the move. The motion controller takes the information and creates the necessary edge profile on point-to-point bases. As a result irregular shape of leather sheet is mapped and is then feed to the controller to calculate surface area.

	+ -	Show Abstract A novel and efficient method called marked bounding box method based on marching cubes is presented for the point cloud data reduction of sole patterns. This method is characterized in that each bounding box is marked with an index during the process of data reduction and later for use of data reconstruction. The data reconstruction is implemented from the simplified data set by using triangular meshes, the indices being used to search the nearest points from adjacent bounding boxes. Afterwards, the normal vectors are estimated to determine the strength and direction of the surface reflected light. The proposed method is used in a sole pattern classification and query system which uses OpenGL under Visual C++ to render the image of sole patterns. Digital results are given to demonstrate the efficiency and novelty of our method. Finally, conclusion and discussions are made.

	+ -	Show Abstract Multiple-exposure-based methods have been an effective means for high dynamic range (HDR) imaging technology. The current methods are greatly dependent on tone mapping, and most of them are unable to accurately recover the local details and colors of the scene. In this work, we present a novel HDR method by using multiple image cues for the image merging process. Firstly, all the images with various exposure times are divided into some uniform sub-regions and an exposure estimation technique is implemented to judge the well exposed one. With all the image blocks have best exposing quality are selected, a blending function is proposed to remove the transition boundaries between these blocks. A fidelity metric index is introduced to assess the final fusion image, and experimental results on public image libraries are given to demonstrate its high performance.

Because of there are sudden vertical steps at the connection points of segment data which will influence the application of road surface data in automotive engineering. So a new smooth connection method of segment test data is proposed which revised the sudden vertical steps connection by the Signal Local Baseline Adjustment (SLBA) method. Besides, there is an actual example which mentioned the detailed process of the smooth connection of segment test data by the SLBA method and the adjusting results at these connection points. The application and calculation results show that the SLBA method is simple and has achieved obvious effect in smooth connection of the segment road test data. The method of SLBA can be widely applied to segment road surface data processing or the long period vibration signal processing.

	+ -	Show Abstract The aim of this paper is to provide the line drawing algorithm which is accurate and effective in dissimilar hardware platforms and different application requirements. The most famous algorithm to draw a straightness line in a smooth fashion is Bresenham algorithm. It is advantageous that the classic Bresenham algorithm processes are all integer numeric without division and decimal fraction. Meanwhile, it is imperfect that the algorithm generates only one pixel at a computation time. So a common inevitable phenomenon of the algorithm is its slow efficiency to some extend. Firstly, this paper fully analyzes recent researches of the Bresenham Line Drawing algorithm. Secondly, in this paper we give full attention to the initiative relation between line generation model and its linear slope, and then we present an improved algorithm which can generate pixels of a line row-major by raster graphics display device. What needs to stress, the core principle of the improved algorithm is utilizing the counterpart of both ends of line and the symmetry for segments. Thirdly, after discussing theory and structure, the improved algorithm implementation and simulation are given. The corresponding project, it means that the hardware acceleration in the use of circular subtraction technology based on shift register was briefly described. Finally, results were presented to demonstrate that the new algorithm inherits the advantage of classic Bresenham algorithm without division and decimal fraction, the speed has been increased greatly, and it is easy to implement by hardware.

	+ -	Show Abstract The current most desirable image retrieval feature is retrieving images based on their semantic content. In order to improve the retrieval accuracy of content-based image retrieval systems, research focus has been shifted from designing sophisticated low-level feature extraction algorithms to reducing the 'semantic gap' between the visual features and the richness of human semantics. In this paper, we put forward a system framework of image retrieval based on content and ontology, which has the potential to fully describe the semantic content of an image, allowing the similarity between images and retrieval query to be computed accurately. In the system, we identify third major categories of techniques in narrowing down the "semantic gap": (1) using object ontology to define high-level concepts; (2) using machine learning methods to associate low-level features with query concepts; (3) using ontology reasoning to extend image retrieval. Finally, the paper does some testing experiment, whose result shows the feasibility of the system framework.

	+ -	Show Abstract This paper aims to solve the problem of detecting ghost object; which is a common problem in background subtraction algorithm. Ghost object is the false object detected which is not corresponding to any actual object in current image. In this work, we proposed ghost detection and removal method using color similarity comparison. Proposed solution is designed based on the assumption that ghost problem occurs due to the existence of the object in background image instead of in the current image. We are using color similarity between detected foreground area and its surrounding area to first determine whether the object appear in background or current image, consequently identify whether the detected object is a ghost or an actual object. Proposed solution has been tested using various datasets including PETS2001 and own datasets and it is proved that the proposed method is able to solve ghost problem.

	+ -	Show Abstract In this paper, a variational method for motion segmentation has been proposed, which is realized by first estimate discontinuity-preserving optical flow field and then segmenting. Specifically, the complementarity between estimation and segmentation was emphasized, so two main improvements were presented: firstly, a segmentation-oriented diffusion tensor has been suggested in the optical flow model, which combines the image and flow information and determine the boundaries more effectively; Secondly, according to the characteristic of vector field, a motion segmentation model with considerations of both motion boundaries and region information were established. The results were illustrated with examples of sequence images which show the usefulness of the proposed approach for various problems.

	+ -	Show Abstract Robust image partitioning technique with limited space-time requirement is crucial for real-time high-resolution mobile imaging applications. Simultaneous handling of color components is a stumbling block in segmentation of color image. This paper presents a strategy for segregating multi-dimensional complexity that resembles human visual perception. First-order regions are developed employing the distribution of base color (hue) creating meaningful partitions of the image. Each region being self-contained can be transmitted independently. Further segmentations on each hue region can be done concurrently with respective local distributions of saturation (S). Finally, each of the subregions can undergo a third-order segmentation based on intensity (I) distribution at local level. Experiments indicate that the segregation process improves throughput and quality of segmentation. Self-contained partitions are convenient for multi-host image sharing as well as progressive reconstruction of images in the receiver.

SPIE 8349, 83490S (2011); http://dx.doi.org/10.1117/12.921075 Online Publication Date: Jan 13, 2012 Full Text: \| Download PDF
	+ -	Show Abstract Automatic brain tissue segmentation is a crucial task in diagnosis and treatment of medical images. This paper presents a new algorithm to segment different brain tissues, such as white matter (WM), gray matter (GM), cerebral spinal fluid (CSF), background (BKG), and tumor tissues. The proposed technique uses the modified intraframe coding yielded from H.264/(AVC), for feature extraction. Extracted features are then imposed to an artificial back propagation neural network (BPN) classifier to assign each block to its appropriate class. Since the newest coding standard, H.264/AVC, has the highest compression ratio, it decreases the dimension of extracted features and thus yields to a more accurate classifier with low computational complexity. The performance of the BPN classifier is evaluated using the classification accuracy and computational complexity terms. The results show that the proposed technique is more robust and effective with low computational complexity compared to other recent works.

	+ -	Show Abstract This paper proposes a Swarm Intelligence based Memetic algorithm for Task Allocation and scheduling in distributed systems. The tasks scheduling in distributed systems is known as an NP-complete problem. Hence, many genetic algorithms have been proposed for searching optimal solutions from entire solution space. However, these existing approaches are going to scan the entire solution space without considering the techniques that can reduce the complexity of the optimization. Spending too much time for doing scheduling is considered the main shortcoming of these approaches. Therefore, in this paper memetic algorithm has been used to cope with this shortcoming. With regard to load balancing efficiently, Bee Colony Optimization (BCO) has been applied as local search in the proposed memetic algorithm. Extended experimental results demonstrated that the proposed method outperformed the existing GA-based method in terms of CPU utilization.

	+ -	Show Abstract An ID-based authenticated group key agreement (AGKA) protocol allows a group of members to share a key and provide an assurance of key sharing with an intended group with the user's identity, which is used for conferencing environments. In 2004, Choi et al proposed an ID-based authenticated group key agreement with bilinear maps (also called CHL protocols), which was extended from Burmester and Desmedt conference key agreement protocols. Unfortunately, their protocols were found to be vulnerable to the insider attacks in which cases that the two malicious users have the previous authentication transcripts of the party by Zhang, Chen and Shim. In this paper, we proposed an improved ID-based AGKA. In our scheme, each session has a unique session identity which is published by Key Generation Center. With such unique session identity binding to each session, our protocols can prevent the insider attack. Especially, our protocols can not enhance the computationally cost and it is still efficient.

	+ -	Show Abstract This paper proposes a new paradigm for the design of cryptographic filesystems. Traditionally, cryptographic file systems have mainly focused on encrypting entire files or directories. In this paper, we envisage encryption at a finer granularity, i.e. encrypting parts of files. Such an approach is useful for protecting parts of large files that typically feature in novel applications focused on handling a large amount of scientific data, GIS, and XML data. We extend prior work by implementing a user level file system on Linux, UsiFe, which supports fine grained encryption by extending the popular ext2 file system. We further explore two paradigms in which the user is agnostic to encryption in the underlying filesystem, and the user is aware that a file contains encrypted content. Popular file formats like XML, PDF, and PostScript can leverage both of these models to form the basis of interactive applications that use fine grained access control to selectively hide data. Lastly, we measure the performance of UsiFe, and observe that we can support file access for partially encrypted files with less than 15% overhead.

However, its training speed and diagnosis speed are relatively slow. Signed Directed Graph (SDG) based on deep knowledge model has better completeness that is knowledge representation ability. However, much quantitative information is not utilized in qualitative SDG model which often produces a false solution. In order to speed up the training and diagnosis of SVM and improve the diagnostic resolution of SDG, SDG and SVM are combined in this paper. Training samples' dimension of SVM is reduced to improve training speed and diagnosis speed by the consistent path of SDG; the resolution of SDG is improved by good classification performance of SVM. The Matlab simulation by Tennessee-Eastman Process (TEP) simulation system demonstrates the feasibility of the fault diagnosis algorithm proposed in this paper.

	+ -	Show Abstract Ever since the concept of analog network coding(ANC) was put forward by S.Katti, much attention has been focused on how to utilize analog network coding to take advantage of wireless interference, which used to be considered generally harmful, to improve throughput performance. Previously, only the case of two nodes that need to exchange information has been fully discussed while the issue of extending analog network coding to more than three nodes remains undeveloped. In this paper, we propose a practical transmission scheme to extend analog network coding to more than two nodes that need to exchange information among themselves. We start with the case of three nodes that need to exchange information and demonstrate that through utilizing our algorithm, the throughput can achieve 33% and 20% increase compared with that of traditional transmission scheduling and digital network coding, respectively. Then, we generalize the algorithm so that it can fit for occasions with any number of nodes. We also discuss some technical issues and throughput analysis as well as the bit error rate.

The obtained gray image was segmented with OTSU threshold method, which made the gray-color abruptly changed pixels along the two sides of the central line identified. Mean value of these selected pixels in each line was calculated to provide the discrete points along the navigation route. Finally least square method was used to fit these discrete points to provide the navigation lines, from which, the route for current navigation scheme can be determined. The proposed algorithm was applied to multiple images for its high speed and anti-noise verification.

At different stages of TC lifetime, the difficulty of locating TC center is different. In order to improve the automatism and precision, we present a TC center location scheme for eye TCs and non-eye TCs. Fisher discriminant is used to segment TC so that we can get the binary image automatically and effectively. Since the cloud wall near the non-eye TC center is homocentric circle, Chan-Vese model is used to get TC contour. Experimental results on TCs show that our scheme can achieve an average error within 0.3 degrees in longitude/latitude in comparison with the best tracks by CMA and RSMC.

	+ -	Show Abstract The active and reactive power decoupling control for the double-fed induction generator wind turbines(DFIG) does not play a positive role to the frequency response ability of power grid because it performs as the hidden inertia for the power grid. If we want to improve the transient frequency stability of the wind turbine when it is integrated with the system, we must ameliorate its frequency response characteristics. The inability of frequency control due to DFIG decoupling control could be overcome through releasing (or absorbing) a part of the kinetic energy stored in the rotor, so as to increase (or decrease) active power injected to the power system when the deviation of power system frequency appears. This paper discusses the mathematical model of the variable speed DFIG, including the aerodynamic model, pitch control system model, shaft model, generator model and inverter control model, and other key components, focusing on the mathematical model of the converters in rotor side and grid side. Based on the existing model of wind generator, the paper attaches the frequency control model on the platform of the simulation software DIgSILENT/PowerFactory. The simulation results show that the proposed control strategy can response quickly to transient frequency deviation and prove that wind farms can participate in the system frequency regulation to a certain extent. Finally, the result verifies the accuracy and plausibility of the inverter control model which attaches the frequency control module.

The application software components which are safety critical may have to be assessed periodically or on demand to achieve not only the functional correctness but also the safety specifications or features while getting executed. The design and deployment of such software modules can be formally verified for possible safety flaws using self checking capabilities and software enzymatic actions. The self checks must sense the safety holes in the software and decide to activate the built-in software components called enzymes to do the safe guard operations in a timely manner to mitigate the safety faults using the proposed enzyme calculus. The various application hazards due to the boolean faults in the functional and behavioral model that lead to software safety issues are considered in this approach.

The paper gives a simple conic spline approximation algorithm for G01 code. The algorithm is mainly formed by three steps: divide the G01 code to subsets by discrete curvature detection, find the polygon line segment approximation for each subset within a given error and finally, fit each polygon line segment approximation with a conic Bezier spline. Naturally, B-spline curve can be obtained by proper knots selection. The algorithm is designed straightforward and efficient without solving any global equation system or optimal problem. It is complete with the selection of curve's weight. To design the curve more suitable for NC, we present an interval for the weight selection and the error is then computed.

	+ -	Show Abstract In this paper, genetic algorithm was used to solve job shop scheduling problems. One example discussed in JSSP (Job Shop Scheduling Problem) and I described how we can solve such these problems by genetic algorithm. The goal in JSSP is to gain the shortest process time. Furthermore I proposed a method to obtain best performance on performing all jobs in shortest time. The method mainly, is according to Genetic algorithm (GA) and crossing over between parents always follows the rule which the longest process is at the first in the job queue. In the other word chromosomes is suggested to sorts based on the longest processes to shortest i.e. "longest job first" says firstly look which machine contains most processing time during its performing all its jobs and that is the bottleneck. Secondly, start sort those jobs which are belonging to that specific machine descending. Based on the achieved results," longest jobs first" is the optimized status in job shop scheduling problems. In our results the accuracy would grow up to 94.7% for total processing time and the method improved 4% the accuracy of performing all jobs in the presented example.

	+ -	Show Abstract The design and implementation of Real-Time Database System is a very complicated issue, a simulator for real-time algorithm research and evaluation is helpful. In this paper, we propose a simulator named AgiSim for real-time transaction scheduling and concurrent control, through which researchers can test, simulate and evaluate many real-time transaction scheduling and concurrent control algorithms. AgiSim is composed of transaction generation component, transaction scheduling component and data management component. The simulator is designed with UML, a state diagram and a sequence diagram of real-time transaction scheduling are given. Two mixed transaction schedulers are designed and simulated in AgiSim.

	+ -	Show Abstract Support vector machine (SVM) was initially used for binary classification. How to generalize the result of two-class classification to multi-class classification has been a problem which needs to be more investigated and studied. A general overview of existing representative methods for multi-category support vector machines was presented and their performances were compared in the paper. Then, the algorithms were applied in the Chinese question classification. Chinese question classification hierarchy and the feature selection of the question were also discussed in the paper. Then, The four algorithms of SVM multi-category classification were applied to Chinese question classification and some contrast experiments were done. The result of the experiments has shown that the binary-tree algorithm is more effective than the other algorithms in the Chinese question classification.

	+ -	Show Abstract Time dependent performance degradation due to negative bias thermal instability (NBTI) is one of the most important reliability concerns for deep nano scale regime VLSI circuits. Under worst case NBTI can degrade circuit performance in terms of timing by more than 10% over a period of 3 years. Reliability decisions taken early in system design can bring significant benefits in terms of design quality. The proposed approach deals with use of latches and NBTI aware scheduling of DFG to overcome the timing violations caused by NBTI. The experimental results suggest that it incurs a very low area overhead and no performance penalty. We propose an algorithm to schedule the DFG and show results for some of the common filters like EW and AR.
