本项目主要工作是对提供图片与库中图片进行颜色和纹理两方面的匹配。其中，颜色匹配直接用基于颜色RGB的直方图匹配，纹理匹配则是通过小波变换转换成频域值，然后用Canny算子计算总和，最后得到图片的纹理图进行匹配(The main work of this project is to match the colors and textures to provide pictures and picture in the library. Among them, the direct use of color matching based on the color RGB histogram matching, texture matching wavelet transform converted into frequency domain values​ ​ , calculate the sum of the Canny operator, and finally get the picture of the texture map to match )
