A Dual Sparse Decomposition Method for Image Denoising
Hong Sun, Chen-guang Liu, Cheng-wei Sang
This article addresses the image denoising problem in the situations of strong noise. We propose a dual sparse decomposition method. This method makes a sub-dictionary decompositio…

Sar image despeckling based on nonlocal similarity sparse decomposition
Chengwei Sang, Hong Sun, Quisong Xia
This letter presents a method of synthetic aperture radar (SAR) image despeckling aimed to preserve the detail information while suppressing speckle noise. This method combines the…

Principal Basis Analysis in Sparse Representation
Hong Sun, Cheng-Wei Sang, Chen-Guang Liu
This article introduces a new signal analysis method, which can be interpreted as a principal component analysis in sparse decomposition of the signal. The method, called principal…
