Abstract

Under the YCbCr color space mechanism

we propose a coupled total variation model for image colorization by combining the gradient of target grayscale image.Then we design a fast algorithm to solve the proposed model numerically by incorporating the alternating direction method of multipliers(ADMM) algorithm

and give the convergence results of the proposed algorithm.Finally

experimental results are reported

demonstrating that the proposed model can effectively prevent colors from crossing over the edges of the target grayscale image during fast colorization.
