d对图片做灰度提取 比如提取ct图像的骨骼等等 大家可以参照一下-d done right Photo Gray ct extracted from images such as the skeleton, and so on we can refer to the

利用快速傅立叶变换实现了人脸表情图像的Gabor变换的快速算法 针对不同尺度的Gabor小波特征采用不同的下采样因子来对Gabor变换特征进行第一次降维 利用一种改进的核鉴别分析方法对Gabor特征进行二次特征提取-using fast Fourier transform of Facial Expression Gabor transform the image of the fast algorithm for different foot the Gabor wavelet characteristics under different sampling factor to the Gabor transform features the first drop Shalikashvili Improved use of nuclear discriminant analysis method Gabor features second feature extraction

这是一个使用域值法编写的图像分割程序，主要是用于学习数字图像处理的同学。-This is a prepared using the threshold method of image segmentation process, mainly for the students to learn digital image processing.

基于Arnold 变换的图像置乱Matlab 程序-Based on Arnold transform image scrambling Matlab procedures

亮度变换在空域上图像的点运算，包括图像增强、亮度对比度调节。-Brightness of the image transform in the airspace of the point calculations, including image enhancement, brightness-contrast adjustment.

（1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 -(1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.
