A new generalized thresholding algorithm for inverse problems with sparsity constraints

Abstract

We propose a new generalized thresholding algorithm useful for inverse problems with sparsity constraints. The algorithm uses a thresholding function with a parameter p, first mentioned in [1]. When p = 1, the thresholding function is equivalent to classical soft thresholding. For values of p below 1, the thresholding penalizes small coefficients over a… (More)
