We propose an algorithm to improve the colorization algorithm using the Lp-norm minimization approach. The proposed algorithm minimizes the Lp-norm of differences between neighboring pixels of a given luminance image to appropriately colorize a chrominance image. Since the Lp-norm minimization problem is difficult to solve, we apply the iterative reweighted least squares (IRLS) algorithm. Numerical examples show the effectiveness of the proposed method.
