| Abstract(in English) | This report proposes a new image colorization algorithm based on the mixed l_0/l_1 norm minimization. Introducing some assumptions, a problem of recovering a color image from a grayscale image with the small number of known color pixels is formulated as a mixed l_0/l_1 norm minimization, which is solved approximately by an iterative reweighted least squares algorithm. Moreover, for improving the quality of colorization, we guess the black and white pixel using the value of grayscale. Numerical examples show that the proposed algorithm colorizes a grayscale image well using a small number of color pixels. |
