摘　　要：针对Image Quilting算法在合成结构性较强的纹理图片时产生局部纹理不连续的问题,提出了一种改进的方法。改进从以下两方面进行:通过图像变形增加样本图的采样空间以增大匹配的概率;改变匹配块的选择策略以提高合成质量。实验结果表明,改进后的算法有效地改善了纹理不连续现象,生成的纹理图像质量更高。In order to solve the discontinuous problem when synthesizing structural texture pictures,an improved method of Image Quilting texture synthesis algorithm was presented. The proposed algorithm was improved in the following two aspects： increasing the sample space of structural information by image morphing to increase the matching probabitity,changing the policy of area matching to improving synthesizing quality.Experimental results show that the proposed algorithm can improve discontinuous phenomenon and obtain a texture picture which has a better quality.
