Despite the acceptable performance of current full-reference image quality assessment (IQA) algorithms, the need for a
reference signal limits their application, and calls for reliable no-reference algorithms. Most no-reference IQA
approaches are distortion specific, aiming to measure image blur, JPEG blocking or JPEG2000 ringing artifacts
respectively. In this paper, we proposed a no-reference IQA algorithm based on the statistic property of principal
component analysis on nature image, named SPCA, which does not assume any specific type of distortion of the image.
The method gets statistics of discrete cosine transform coefficients from the distort image’s principal components. Those
features are trained by -support vector regression method and finally test on LIVE database. The experimental results
show a high correlation with human perception of quality (averagely over 90% by scores of SROCC), which is fairly
competitive with the existing no-reference IQA metrics.
In the view of the blindness of photoelectric measurement scheme argument and the danger of live shell measurement in shooting range, this paper provided a computer aided measurement method guiding the measurement scheme argument and equipment researching and producing and driving the measurement process visiblization and standardization. The computer aided measurement in shooting range can be divided into the mathematical simulation of targets moving, the mathematical simulation of measurement method, the mathematical simulation of photoelectric system, the animated displaying of measurement process, and so on. By adding random jamming, Gaussian white noise and so on, the live measurement environment and condition was built. By using mathematical discretization, the time series pictures was obtained. By controlling the time changing and time unifying of several equipment, the animated displaying of measurement process was built. The programming language was MATLAB. The method was proved through simulating the intersection measurement trajectory of antiaircraft gun's shell successfully.
