Simultaneous Patch-Group Sparse Coding with Dual-Weighted <i>ℓ</i><sub>p</sub> Minimization for Image Restoration

Sparse coding (SC) models have been proven as powerful tools applied in image restoration tasks, such as patch sparse coding (PSC) and group sparse coding (GSC). However, these two kinds of SC models have their respective drawbacks. PSC tends to generate visually annoying blocking artifacts, while G...
