摘要: 基于样图的纹理合成方法是继纹理映射、过程纹理合成等方法后发展起来的一种纹理拼贴方法。该文在Efros块拼贴算法和徐晓刚的螺旋状点匹配搜索算法基础上,提出了一种螺旋状匹配搜索的块拼贴算法。该算法利用纹理块的连惯性,在搜索待合成纹理块时,在已合成纹理块在样本图像中位置的邻域进行搜索,找到匹配纹理块后进行输出。该方法大大加快了纹理合成的速度,与Efros块拼贴算法相比,在合成质量不变的基础上,合成速度平均提高了10倍。对于不同的纹理进行实验,其结果也令人满意。

Abstract: The texture synthesis from samples is a texture quilting method, which is developed after the proposal of procedural texture synthesis and texture mapping method. This paper presents a new approach for texture synthesis matching patch along a spiral path with the help of "texture consistency". The algorithm searches for new matching patch among the neighbors of the previous matched patch along a spiral path and continues this process in a recursive manner until the synthesizing image is fully filled. Compared with the Efros approaches under synthetic quality constant condition, the velocity, the synthesizing process of our technique, has raised 10 times in average. Experiments show that synthesizing results are quite satisfactory.
