Abstract: In recent years,with the rapid development of computer technology,such as multimedia technology and computer vision research,espelially popular color image capture device,color image has been more and more widely used in various fields of society.For the nature of color images,this paper proposed a recursive enhancement algorithm based on the theory of LIP.The core idea of the algorithm is that in the RGB color space images the proportional relationship between the different components of different pixel is investigated.In addition,under the LIP framework,each pixel was amplied,achieving the color image enhancement.
