Existing regularization functions for color image restoration cannot remove color artifact, undesirable appearance of colors, sufficiently, which degrades the quality of color images. In this paper, we propose a new regularization function, named the local color nuclear norm (LCNN), for removing color artifact in color image restoration. LCNN is designed to promote the local color-line property: the color distribution of each local region of a color image exhibits strong linearity. The local… CONTINUE READING
