摘　　要：分析了块纹理合成方法中纹理块尺寸对合成结果的影响,经过对大量不同类型纹理图像采样,归纳并验证了纹理相关性特征值与纹理块尺寸之间的关系,得出纹理相关性特征值自适应调整纹理块尺寸的算法.采用该算法可避免因纹理块尺寸选取不当而引起的合成时间的增加和合成质量的降低.This paper investigates the effects of the size of the candidate patches on the final results of texture synthesis. Based on substantive analysis of various texture images, we found the relationship between texture relativity value and the size of a texture patch. We propose a novel approach to adaptively adjust the size of the candidate texture patches based on their texture relativity values, successfully preventing the increase of synthesis time and the degradation of synthesis quality caused by improper selection of the size of the candidate texture patches.
