The existing compressed sensing image reconstruction algorithms cannot combine reconstruction effect with reconstruction speed at the same time. A new image reconstruction algorithm is proposed for compressed sensing. The new algorithm retains the advantages of block-sampling compressed sensing by the image blocks segmentation. The subblocks of the image edges are extracted and then the edges structure...
Synthetic aperture radar (SAR) images are inherently affected by speckle noise, which is due to the coherent nature of the scattering phenomenon. This paper presents a novel SAR speckle reduction method base on nonlocal means (NLM) filter. NLM is applied to remove additive noise after taking the logarithm of the original speckle noise. The proposed method can preserve edges and protect more fine details...
Stereo correspondence is the key approach to recover range information in stereo vision. Considering area matching and feature matching, the stereo correspondence approach based on edge feature is proposed in this paper. As the research object controlled by threshold binary domain, the procedure of correspondence is fulfilled by matching constraint and iterative operation, and algorithm mentioned...
