A nonconvex $$\hbox{TV}_q-l_1$$ TV q - l 1 regularization model and the ADMM based algorithm
Abstract The total variation (TV) regularization with $$l_1$$ l 1 fidelity is a popular method to restore the image contaminated by salt and pepper noise, but it often suffers from limited performance in edge-preserving. To solve this problem, we propose a nonconvex $$\hbox{TV}_q-l_1$$ TV q - l 1 re...
