Abstract
A method for converting monochrome images to color images. A monochrome image is blocked first, and pixel values of monochrome image blocks are obtained by statistical analysis. The monochrome image is then processed by layered mapping and color values of equal grayscale layers thereof are obtained. Finally, each monochrome image block is matched to a color of a corresponding equal grayscale layer.
