A Colorization Algorithm for Gray Images Based on Image Segmentation and Color Propagation

This paper introduces a technique for colorizing the grayscale images.First,the source grayscale image and the target image are segmented using the Mean-Shift algorithm.Then,part color of the source image is transferred to the target image between each matching blocks in lαβcolor space. At last the part colors are automatically propagated to produce a fully colorized target image.This technique can be completed automatically and the result is very well.
