Color Image and Multispectral Image Denoising Using Block Diagonal Representation

11 Feb 2019 Zhaoming Kong Xiaowei Yang

Filtering images of more than one channel is challenging in terms of both efficiency and effectiveness. By grouping similar patches to utilize the self-similarity and sparse linear approximation of natural images, recent nonlocal and transform-domain methods have been widely used in color and multispectral image (MSI) denoising...
