摘　　要：提出一种改进的基于样图的块拼贴纹理合成算法.针对拼贴纹理块时产生的局部性边界不匹配现象,用图的切割算法寻找块重叠区域的最优拼接路径,有效地提高了纹理合成质量.同时采用多分辨率图像金字塔构建输入纹理图像,并结合螺旋线搜索策略和加速算法提高纹理合成速度.In this paper, we present an improved texture synthsis method based on patch-based synthesis. In order to solve the local areas donnot match phenomenon which been caused by patch-based synthesis. We adopt graph eut algorithm to compute the best patch-based synthesis path between the overlaps. The method efficaciously improved the quality of texture synthesis. Simultaneity, we adopt multiresolution image pyramid to build the input texture image, also combine spiral search strategy and acceleraterion algorithm to improve the speed of texture synthesis.
