Abstract: With regard to the problem of spending too much time and easily having joints existed in texture synthesis algorithm of Ashikhmin，this paper presents a improved texture synthesis algorithm based on principle of the relevance.The algorithm has been extended Ashikmin algorithm from pixel-based texture synthesis to the patch-based texture synthesis，and uses new error metrics，speeding the matching process and the effect of texture synthesis more in line with the vision requirement.The simulation experiments verify the effectiveness of this algorithm.
