摘　　要：为了弥补现有纹理种类的不足,将螺旋状匹配搜索的块拼贴纹理合成方法和Ashikhmin的点匹配方法相结合,应用到设计图案的纹理合成．与Ashikhmin的点匹配方法相比较,该方法的效率提高了5倍以上,并且避免了纹元错位、条带化现象．In order to make up for the deficiency of the existing texture type, the authors synthesize novel textures using existing textures by according to the patterns designed to enrich the category of the texture. The patch-based texture synthesis and the pixel-based texture synthesis are combined by adopting the patchbased texture synthesis that searches matching patch along spiral path and Ashikhmin＇s pixel-based texture synthesis. Compared with the Ashikhmin＇s approach, the speed of the authors＇ approach has been raised more than 5 times and the synthesizing results have avoided strip and noticeable seams of the pattern.
