Deep Exemplar-based Colorization

This is the implementation of paper Deep Exemplar-based Colorization by Mingming He*, Dongdong Chen*, Jing Liao, Pedro V. Sander and Lu Yuan in ACM Transactions on Graphics (SIGGRAPH 2018) (*indicates equal contribution).

Deep Exemplar-based Colorization is the first deep learning approach for exemplar-based local colorization. Given a reference color image, our convolutional neural network directly maps a grayscale image to an output colorized image.

Deep-Exemplar-based-Colorization

The proposed network consists of two sub-networks, Similarity Sub-net which computes the semantic similarities between the reference and the target, and Colorization Sub-net which selects, propagates and predicts the chrominances channels of the target.

The input includes a grayscale target image, a color reference image and bidirectional mapping functions. We use Deep Image Analogy as default to generate bidirectional mapping functions. It is applicable to replace with other dense correspondence estimation algorithms.
