数字图像处理冈萨雷斯matlab版，讲述了如何用matlab进行图像处理，是一本经典教程。(Gonzalez digital image processing matlab version, describes how to use matlab image processing, is a classic tutorial.)

可以直接计算信号的四阶累计量，挺不错的小程序，注意信号必须是非高斯信号哟。(Signals can be directly calculated fourth-order cumulant, very good small procedures, the attention signal must be a non-Gaussian signal yo.)

this is the DCT image compression code i have tried . i missed out 2 files while uploadin last time sorry :) hey guys i missed 2 files
