Image denoising using group sparsity residual and external nonlocal self-similarity prior
Zhiyuan Zha, Xinggan Zhang, Qiong Wang +2
Nonlocal image representation has been successfully used in many image-related inverse problems including denoising, deblurring and deblocking. However, a majority of reconstructio…

Image denoising via group sparsity residual constraint
Zhiyuan Zha, Xin Liu, Ziheng Zhou +7
Group sparsity has shown great potential in various low-level vision tasks (e.g, image denoising, deblurring and inpainting). In this paper, we propose a new prior model for image…
