Analyzing the group sparsity based on the rank minimization methods
Zhiyuan Zha, Xin Liu, Xiaohua Huang +5
Sparse coding has achieved a great success in various image processing studies. However, there is not any benchmark to measure the sparsity of image patch/group because sparse disc…

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…

A Comparative Study for the Nuclear Norms Minimization Methods
Zhiyuan Zha, Bihan Wen, Jiachao Zhang +2
The nuclear norm minimization (NNM) is commonly used to approximate the matrix rank by shrinking all singular values equally. However, the singular values have clear physical meani…
