彩色图像的威纳滤波去噪算法，很简单的，很全，自己毕业论文的程序(Color image of the Wiener filter denoising algorithm, very simple, very full, their thesis program)

介绍ransac的matlab程序，用在图形图像基于特征点的配准中 可以有效的剔除错误的匹配点 (介绍ransac的matlab程序，用在图形图像基于特征点的配准中 可以有效的剔除错误的匹配点 )

Image enhancement is a processing on an image in order to make it more appropriate for certain applications. It is used to improve the visual effects and the clarity of image or to make the original image more conducive for computer to process. Contrast enhancement changing the pixels intensity of the input image to utilize maximum possible bins. We need to study and review the different image contrast enhancement techniques because contrast

此程序为用于jpeg2000中的小波零树压缩编码，它采用了小波零树编码原理，利用了小波系数之间的关系(this procedure for the jpeg2000 EZW coding, It uses wavelet zerotree coding theory, the use of wavelet coefficients of the relationship between)
