摘要：This paper presents a novel technique using clustering preprocessing for the challenging problem in the field of computer graphics, which is to speed up texture synthesis without losing of synthesis quality and adding of method complexity. An algorithm of rapid texture synthesis based on clustering preprocessing is designed to speed up both of pixels-based and patch-based local region-growing methods maintain original level of texture quality or gaining better. Experiments show that efficiency of pixel-based texture synthesis method with respect to stochastic texture sample increases by 80 percent with better synthesis quality, and efficiency of patch-based texture synthesis method with respect to structured texture sample increases by 70 percent. Due to avoiding the step of blending the overlap pixels needed by patch-based texture synthesis the synthesis quality is more steady than original results.
