Research of Color Matching Method Based on BP Network

Color matching method is one of the key technologies in the computer graphics and image processing fields. A color matching method based on BP network, BP _CMM, is presented in this paper and it not only can solve the nonlinear conversion form RGB color space to CMYK color space but also can be applied to complete conversion between other two different color spaces. Firstly, the selecting criterion and the transforming method of sample data are given, and clustering the sample data is achieved with the iterative self organizing data analysis technique algorithm relating to the properties of color matching. Then, in the course of applying BP network to color matching method, designing the reasonable network structure and standardizing the data are discussed. Finally, the network training and testing results are given and the experimental results show that BP\-_CMM is satisfactory.
