Group Sparsity Residual with Non-Local Samples for Image Denoising

22 Mar 2018Zhiyuan ZhaXinggan ZhangQiong WangYechao BaiLan TangXin Yuan

Inspired by group-based sparse coding, recently proposed group sparsity residual (GSR) scheme has demonstrated superior performance in image processing. However, one challenge in GSR is to estimate the residual by using a proper reference of the group-based sparse coding (GSC), which is desired to be as close to the truth as possible... (read more)
