A doubly sparse and low-patch-rank prior model for image restoration

•A unified doubly sparse and low-patch-rank prior model including two complementary sparse terms and one nuclear norm term.•A new low-patch-rank minimization model without total variation regularization.•An implementable three-block alternating minimization algorithm with global convergence and O(1/...
