The restoration of images corrupted by blurring and multiplicative noise is a challenging problem in applied mathematics that has attracted much attention recent years. In this article, we propose two-step approach to solve the restoring degraded blurring, where first reduced nonlocal filters then convex variational model adopted obtain final restored images. second step composed an $L_1$-$L_2$ data-fidelity term total variation regularization term. alternating direction method (ADM)...
Small target detection is a crucial and challenging task in infrared search track system. Background estimation-based methods an effective important approach for small detection. Affected by the pixels, existing background estimation may reconstruct inaccurate background. Based on image inpainting technique, we propose novel two-stage to predict more accurate backgrounds. At first stage, inner outer window-based (IOWII) used obtain rough estimation. Then mask of candidate region...
Infrared small target detection is an important and core problem in infrared search track systems. Many methods work well under the premise of a static background; however, effect decreases seriously when background changes dynamically. In addition, spatiotemporal information image sequence are not fully developed utilized, lacking long-term temporal characteristics. To solve these problems, novel spatial–temporal tensor (LSTT) model proposed this paper. The registration technique employed...
