Abstract: In order to solve the authenticity identification algorithm’s problem of low accuracy and large amount of calculation in Chinese painting based on pixel level, this paper proposes a regional level belief propagation algorithm. The image is divided into blocks which is introduced into the basic belief propagation algorithm, excluding non-important information in the transmission process of regional block message. Through the region units and eight surrounding directions, confidence function can be iteratively calculated in the basis of information transmitting and the authenticity of the image block can be reasoned, and then the state of the authenticity of all kinds of subjects is determined. The experiment results show that the improved algorithm can promote the original algorithm for the accuracy of the image recognition and the algorithm’s operation rate.
