In this paper, we focus on the research of fast deconvolution algorithm based on the non-convex L"q(q=12,23) sparse regularization. Recently, we have deduced the closed-form thresholding formula for L"1"2 regularization model (Xu (2010) [1]). In this work, we further deduce the closed-form thresholding formula for the L"2"3 non-convex regularization problem. Based on the closed-form formulas for L"q(q=12,23) regularization, we propose a fast algorithm to solve the image deconvolution problem… CONTINUE READING
