图形常见变换如维纳、中值滤波 小波变换,加噪,复原等处理要求图像为256色-common graphics transformation as Wiener, the median filter wavelet transform, increase noise, rehabilitation processing requirements for the 256 color images
视频处理中最重要的指标:PSNR(峰值信噪比)。本人写的一个小程序,用于测试图象中的Y、U、V分量的PSNR值。-PSNR is a very important index in video disposal.
there are a little program . It tests the PSNR of the YUV in the image.
