Research on the Color Reproduction Based on the BP Neural Network Algorithm

This paper proposes an algorithm of BP neural network, which reproduces a color image under D65 light conditions by using a pair of images (one with no D65 light source, and the other with D65 light source). The result of reproduction image which used a fluorescent lamp as an unknown light source is presented. This algorithm successfully removes the effect of the unknown light source color and achieves color constancy at a practical computational cost. The experiment results show that the validity of the proposed algorithm.
