纹理合成算法的计算中，用像素权值代替像素的RGB值来计算误差，该算法改进的实验效果并不理想，可以下载后运行观察实验效果。-Texture synthesis algorithm calculations, the right to use pixel values instead of pixel RGB values to calculate the error, the algorithm is improved experimental results were not satisfactory, you can download to run after observation of experimental results.
