Robust Estimation of 3D Human Poses from a Single Image
Chunyu Wang, Yizhou Wang, Zhouchen Lin +2
Human pose estimation is a key step to action recognition. We propose a method of estimating 3D human poses from a single image, which works in conjunction with an existing 2D pose…
Exploring Algorithmic Limits of Matrix Rank Minimization under Affine Constraints
Bo Xin, David Wipf
Many applications require recovering a matrix of minimal rank within an affine constraint set, with matrix completion a notable special case. Because the problem is NP-hard in gene…
Group-based Sparse Representation for Image Restoration
Jian Zhang, Debin Zhao, Wen Gao
Traditional patch-based sparse representation modeling of natural images usually suffer from two problems. First, it has to solve a large-scale optimization problem with high compu…
Image Restoration Using Joint Statistical Modeling in Space-Transform Domain
Jian Zhang, Debin Zhao, Ruiqin Xiong +2
This paper presents a novel strategy for high-fidelity image restoration by characterizing both local smoothness and nonlocal self-similarity of natural images in a unified statist…
Image Compressive Sensing Recovery Using Adaptively Learned Sparsifying Basis via L0 Minimization
Jian Zhang, Chen Zhao, Debin Zhao +1
From many fewer acquired measurements than suggested by the Nyquist sampling theory, compressive sensing (CS) theory demonstrates that, a signal can be reconstructed with high prob…
Structural Group Sparse Representation for Image Compressive Sensing Recovery
Jian Zhang, Debin Zhao, Feng Jiang +1
Compressive Sensing (CS) theory shows that a signal can be decoded from many fewer measurements than suggested by the Nyquist sampling theory, when the signal is sparse in some dom…
