Image sequence colorization based on motion estimation and color revising

Abstract

Colorization is a computer-assisted technique of adding colors to monochrome images, movies or TV programs. This paper proposes a colorizing scheme for image sequences based on motion estimation and color revising. First the motion vector is refined by a block based neighborhood relaxation. Then the color transfer is established between image sequences. To remove the incorrect colors may occurred during the color transfer, a color revising method is put forward, which consists of image segmentation, region merging, error detection and correction. This colorization scheme has been tested with real image sequences and the results demonstrate its validity and efficiency.
