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…
Analyzing the Affect of a Group of People Using Multi-modal Framework
Xiaohua Huang, Abhinav Dhall, Xin Liu +4
Millions of images on the web enable us to explore images from social events such as a family party, thus it is of interest to understand and model the affect exhibited by a group…
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…
Spontaneous Facial Micro-Expression Recognition using Discriminative Spatiotemporal Local Binary Pattern with an Improved Integral Projection
Xiaohua Huang, Sujing Wang, Xin Liu +3
Recently, there are increasing interests in inferring mirco-expression from facial image sequences. Due to subtle facial movement of micro-expressions, feature extraction has becom…
