Mesh parameter optimization for images colorization scheme

Colorization is a process of adding color to a monochrome image or movie. In order to color the grayscale images and minimize the amount of human labor required. Welsh is to transfer color to a grayscale image from a color image. Though the method is simple and easy to realize, the shortcoming is that the speed is relatively slow, and may get the wrong color because of the wrong compare. The methods of Levin and Yatziv color a image only need people to annotate the image with a few color scribbles. In image painting systems, the underlying surface parameterization is fixed during the painting process. Such a parameterization is not sensitive to the frequency spectrum of the color signal introduced by painting strokes. To associate the regions of higher color signal variation with more texture samples, re-parameterization according to user strokes at interactive rates is necessary. It provides a method to produce re-parameterization scheme to solve above problems. The results can demonstrate our method that is convenient and practical.
