基于耦合全变差的快速图像着色算法
A Fast CoupIed TotaI Variation AIgorithm for I mage CoIorization
摘要
Abstract
Under the YCbCr color space mechanism,we propose a coupled total variation model for image coloriza-tion by combining the gradient of target grayscale image.Then we design a fast algorithm to solve the proposed model nu-merically by incorporating the alternating direction method of multipliers(ADMM)algorithm,and give the convergence re-sults of the proposed algorithm.Finally,experimental results are reported,demonstrating that the proposed model can effec-tively prevent colors from crossing over the edges of the target grayscale image during fast colorization.关键词
