A Benchmark for Sparse Coding: When Group Sparsity Meets Rank Minimization
Published 12 Sep 2017 in cs.CV | (1709.03979v5)
Abstract: Sparse coding has achieved a great success in various image processing tasks. However, a benchmark to measure the sparsity of image patch/group is missing since sparse coding is essentially an NP-hard problem. This work attempts to fill the gap from the perspective of rank minimization. More details please see the manuscript....
