Small target detection in the clutter infrared image is a tough but significant work. In this paper, we will propose a novel
small target detection method. First, Graph Laplacian regularization is utilized to model similarity feature of graph
structure in the image. And Graph Laplacian regularization is incorporated in the background estimation model to
preserve edges of background in single frame infrared image. At last, the edge-preserving estimated background is
eliminated from original image to get foreground image which is used to detect the small target. Experimental results
show that our proposed method can achieve edge-preserving estimation of background, suppress clutter efficiently, and
get better detection results.
WO3 has emerged as one of the most extensively studied materials because its gasochromic effect can be used for
smart window and gas sensor; currently it is widely used in many energy conservation areas. Compared with other
preparations methods for gasoschromic films, sol-gel process shows several advantages, such as low cost and large-scale
applications. However, sol-gel WO3 films were not stable enough for commercial application yet. In this paper, we first
investigated the effect of SiO2 doping, which exhibited good enhancement of WO3 gasochromic films' stability. We also
examined the relationship between SiO2 ratio and stability of WO3/SiO2 films. An empirical formula was established by
fitting exponential decay of the coloring-bleaching cycles for four different Si/W ratios.
