关于图像小波边缘检测的MATLAB程序，用于一般图像边缘检测(wavelet-edge)

三帧差分法，绝对可用，matlab实现，里面有视频和结果图。如果程序出错误，可用先把result.avi删除，在做测试、(Three difference method, absolutely free, matlab realize, there are videos and results map. If the program is an error that can be used to delete first result.avi while doing the test,)

Viola-Jones Fast Face Detection的matlab实现。(Viola-Jones Fast Face Detection Mex Implementation)

retinex算法的一个源代码，用于图像增强处理，能比较好的提高对比度(retinex an algorithm source code for image enhancement, to better enhance the contrast)

高光谱图像进行MNF变换，采用MAF评价图像的噪声；处理过程与ENVI软件中的完全一样。(MNF transformation of hyperspectral images, using noise MAF to evaluate the image.the process is exactly the same with ENVI software .)

本程序实现了基于对比金字塔的图像融合算法，效果还不错，可以参考一下。(This procedure contrast pyramid based on the implementation of image fusion algorithms, the effect was not bad, you can reference.)

基于matlab的钢筋计数方法，有ui界面(MATLAB-based steel bar counting method with UI interface)

图像着色处理，对于不同亮度的图像显示不同颜色，应用于水下声纳图像效果比较好。(Image color processing, to the image shows different colors of different brightness, applied to the underwater sonar image effect is better. )

用图切分（Graph_Cut）分割图像彩色图像、灰度图像及二值图像，效果较好，尤其是金相组织图像的分割更加有效。(Graph_Cut)

　　本函数选用阈值分割的方法来完成瞳孔定位。根据图像的灰度分布特性，瞳孔部分的灰度值最小，其次为虹膜部分，最大的为巩膜部分。因此在灰度直方图中，第一个大峰值的邻域即是瞳孔所在区域。(Function selects the threshold segmentation method to accomplish the pupil location. Based on image gray distribution features, the pupil part of the grey value of the minimum, followed by the iris part, the biggest part of sclera. So in gray level histogram, the peak value of the first big neighborhood is the pupil area.)
