Blind Image Deblurring via Reweighted Graph Total Variation
Yuanchao Bai, Gene Cheung, Xianming Liu +1
Blind image deblurring, i.e., deblurring without knowledge of the blur kernel, is a highly ill-posed problem. The problem can be solved in two parts: i) estimate a blur kernel from…
Joint Denoising / Compression of Image Contours via Shape Prior and Context Tree
Amin Zheng, Gene Cheung, Dinei Florencio
With the advent of depth sensing technologies, the extraction of object contours in images---a common and important pre-processing step for later higher-level computer vision tasks…
Graph Fourier Transform with Negative Edges for Depth Image Coding
Weng-Tai Su, Gene Cheung, Chia-Wen Lin
Recent advent in graph signal processing (GSP) has led to the development of new graph-based transforms and wavelets for image / video coding, where the underlying graph describes…
