Abstract: Color transfer is an effective approach to change the color of the image. Traditional methods mostly adopt single source image, so there is big limitation in actual application. This paper presented a color transfer techniques with multi-source images. This method chose the best-matched source colors for re-coloring each target region, by a series of operation, for example, brightness re-mapping; referencing color area; transferring synthesis and so on. Then, different transferring synthesis methods were given according to different color images and grayscale images. Finally, this paper achieved color transferring to every target area. Using colorfulness as the evaluation index, the experiments show that the proposed method can generate convincing results with better performance.

Key words: color transfer, brightness re-mapping, reference color area, transfer synthesis
