An Efficient Algorithm for ℓ 0 Minimization in Wavelet Frame Based Image Restoration

Abstract

Wavelet frame based models for image restoration have been extensively studied for the past decade [1, 2, 3, 4, 5, 6]. The success of wavelet frames in image restoration is mainly due to their capability of sparsely approximating piecewise smooth functions like images. Most of the wavelet frame based models designed in the past are based on the penalization… (More)
