图像水平垂直投影的Matlab程序，图像水平垂直投影的Matlab程序。...

基本的图像处理，包括线性变换，如灰度平衡。

（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.

可以实现屏幕的截图功能，由点简单，但是很实用，可以下载用-Screen shots can be functional, by the point is simple, it is very practical and can be downloaded with

LSB数字水印以及文件隐藏。（只针对24位BMP)-LSB digital watermarking

包括了常用的图象处理操作,包括平滑,锐化,边缘提取等等!值得一看!-including the common image processing operations, including smoothing, sharpening, edge extraction and so on! An eye-catcher!

这篇文章是发表在08年ACM上的一篇图像检索综述，作者是PSU大学的博士毕业生，作者参考了300多篇文献，非常细致的讲述了image retrieval近几年的算法，方法，以及发展方向。-This article was published in the 2008 ACM on an image retrieval review, the author is a Ph.D. graduate PSU University, the authors made reference to more than 300 literatures, very careful about the image retrieval in recent years, algorithms, methods, and direction of development.

基于环形颜色直方图的图像检索算发，比传统方法好用的多-Annular color histogram-based image retrieval count hair, easy to use than the more traditional methods

flash导航条，大家在网站设计的时候经常会遇到如何设计自己导航条的问题，一些精美的导航条实例给大家-flash navigation bar, web design in the U.S. often encounter how to design their own navigation bar, some fine examples of the navigation bar to the U.S.

JPEF格式的图像处理，我会相继上传多种格式的图像处理源码，希望共同探讨。-JPEF format image processing, I will have upload multiple format of image processing source, hoping to explore.
