Non-Local Robust Quaternion Matrix Completion for Color Images and Videos Inpainting. (arXiv:2011.08675v3 [cs.CV] UPDATED)

The image nonlocal self-similarity (NSS) prior refers to the fact that a
local patch often has many nonlocal similar patches to it across the image and
has been widely applied in many recently proposed machining learning algorithms
for image processing. However, there is no theoretical analysis on its working
principle in the literature. In this paper, we discover a potential causality
between NSS and low-rank property of color images, which is also available to
grey images. A new patch group …
