JIN Zheng-meng, ZHOU Chen. A Fast Coupled Total Variation Algorithm for Image Colorization[J]. Acta Electronica Sinica, 2016, 44(10): 2364-2369. DOI: 10.3969/j.issn.0372-2112.2016.10.012.
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.
