一片图像分割的硕士毕业论文，很有新意，希望对大家有帮助。-Image segmentation of a master

（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.

数字图像处理中常用的DCT算法，是傅氏变换的一个变种，VC编写，包含完整源代码与实例图片-Commonly used in digital image processing of the DCT algorithm is a variant of Fourier transform, VC preparation that contains complete source code and examples of image

该工程项目实现了AR算法，提供签名在线鉴别功能-The project achieved the AR algorithm, to provide online identification function signature

这是一个人脸检测代码，在VC下编写的，本人感觉对图像处理专业的同学非常有用，特地拿来分享-This is a face detection code, prepared in the VC, I feel for the image processing professional students very useful, specially used to share

这个基于分割得图像增强程序，试验图片是256×256大小-based segmentation in the image enhancement procedures, test image is the size of 256 256
