Image Colorization Based on Color Transfer and Propagation

Abstract

The color uniformity is one of the important problems that haven't been solved with the color transferring technique yet.Some traditional methods of the color transferring between images are based on the pixels matching.These methods can't ensure that the color of the colorized image feels well.In other words,it means that the color of some pixels is distinct from the color of their neighbors in the colorized target images.This paper presents an image colorization method based on color transfer and propagation.First,it obtains a part-colored image from transferring color to the grayscale image using traditional technique in the lαβ color space.Then it makes the local colors be automatically propagated to produce a fully colorized image.In experiments,the color of the colorized images obtained is very good and the results demonstrate the practicality of this method.
