Image denoising using group sparsity residual and external nonlocal self-similarity prior

3 Jan 2017Zhiyuan ZhaXinggan ZhangQiong WangYechao BaiLan Tang

Nonlocal image representation has been successfully used in many image-related inverse problems including denoising, deblurring and deblocking. However, a majority of reconstruction methods only exploit the nonlocal self-similarity (NSS) prior of the degraded observation image, it is very challenging to reconstruct the latent clean image...
