Implementation code for wavelet domain image inpainting using nonlocal total variation algorithm, based on "WAVELET INPAINTING BY NONLOCAL TOTAL VARIATION" by Xiaoqun Zhang and Tony F. Chan, Inverse Problems and Imaging, 2010, 4(1). This MATLAB implementation combines wavelet decomposition with nonlocal regularization for effective image restoration.
