Abstract:

In this paper, we propose a total variation (TV) model with depth image priors for image colorization. Under the plug-and-play (PnP) framework, we design the numerical algorithm to solve the model by incorporating the alternating direction method of multipliers (ADMM), and give the convergence result of the algorithm. The experimental results show that the model can effectively integrate the edge capture function of coupled TV and the detail capture function of convolutional neural network (CNN), and also can achieve a large scale effective coloring for structural images and multi textures detailed images.

Key words: image coloring, coupled total variation (TV), convolutional neural network (CNN), plug-and-play (PnP) framework, alternating direction method of multipliers (ADMM)
