用matalab编译的winner滤波法对图像进行去噪处理，利用了FFT的方法(Compiled using matalab winner filtering method to deal with the noise of image, using the FFT method )

一个去水印的程序，已调好。里边包含实例图片，可以帮助大家理解这个代码。(A program to watermark has a good tune. Inside contains examples of pictures that can help us to understand the code.)

说明：  PWLS算法主要用于CT重建前的投影数据处理，能够很好的用于CT迭代算法中，对图像进行去噪(PWLS algorithm is mainly used for projection data processing before CT reconstruction. It can be well used in CT iterative algorithm to denoise images.)

在使用envi中的band_math时需要将两张图像设置为相同的行和列，改程序解决了该问题(In use of envi band_math need two images set to the same rows and columns, change the program to solve the problem)

说明：  给图像加高斯白噪声,里面有详细的代码，我不知道该说些什么，只是觉得很好(gaussian noise Why must I be forced to write so many words?)

说明：  对加载的图像进行灰度处理，简单处理matlab程序，效果不错，利于后面对图形进一步加工处理(Gray-scale processing of loaded images)

维的简单LDA和2维LDA人脸识别的matlab代码，注释详细，可以直接运行，非常好用，还有1维LDA算法讲解，很适合入门的同学！( U7EF4 u7684 u7352 u5355 u548C2 u7A4 u7A1 UFF0C u9H09 u5976 u5E8 u5L0 u5B0 )

运用matlab在遥感图象上运用神经网络方法进行图像分类(Using matlab to classify remote sensing images using neural network method)

LLE算法，matlab源码，LLE算法是流形学习算法的一种(LLE algorithm, matlab source, LLE algorithm manifold learning algorithm is a)

用小波变换进行图像增强，先对原始图像进行非下采样的小波分解，在对每一层的高频分解系数进行处理，得到变换后的小波系数，再进行小波重构。(Image enhancement using wavelet transform, the original image and non-sampling wavelet decomposition in the high frequency decomposition coefficients of each layer, get the wavelet coefficients after the transformation, then the wavelet reconstruction. )
