Image Color Processing Baded On Image Library

Image color process is always one important aspect of image process. Color gradient plays a crucial role in image color process. Generally, it means transition between colors. In this paper, image color gradient uses the color gradient ring created by the template image color information to match the source image black-white grayscale ring. Color match provides the users the opportunity to involve in the color match process and offers users more flexibility. By taking part in color match, users can define their own color match themes. The using of images library not only enhances expansibility, but also improve the practical applicability of color process.This paper addresses the problem of images color processing based on images library. Besides as the source of images, images library also provide the filter of images by their color themes. The image color gradient is completed by match the color ring of template image to the grayscale source image. The input of color match to our algorithm is a sparse set of desired color correspondences between a source and a target image. The global color space transformation problem is then solved by computing the dimensions in HSL color space changes by RGB color space that maps the gamut of the source to that of the target. Finally we realize a color process system which provides user retrieves, image color gradient and image color match.
