matlab实现的小波降噪声图像处理算法，效果十分好，自己做了调试。(The wavelet reduced noise image processing algorithm realized by Matlab is very effective and has been debugged.)

说明：  可以用来评价一幅图像是否清晰，清晰度是多少。(It can be used to evaluate whether an image is clear and how clear it is.)

说明：  对图像进行伽马校正，可以有效提升图像 亮度和对比度，低于低照度图像现在小于1的参数，对于高亮度的图像选择大于1的参数可以有效调节图像亮度。(Gamma correction can effectively improve the brightness and contrast of the image. The parameters lower than the low illumination image are less than 1. For the high brightness image, the selection of parameters greater than 1 can effectively adjust the brightness of the image.)

阴影检测,基于OpenCV用于对图像中阴影的检测(Shadow detection, OpenCV for image shadow detection)

用AAM算法进行人脸特征点的标定，即对人脸的眼睛，眉毛，嘴巴，鼻子及脸的轮廓进行标记，此代码标记了68个特征点。(AAM algorithm for facial feature points calibration, calibration of this code is the 68 feature points, see the instance document.)

用matlab编写的用于提取图像纹理特征提取

利用该函数可以对图像进行仿射变换，是不错的matlab源代码(Function can make use of the image affine transformation, is a good source code matlab)

pca 主成分分析c 代码和原理文档。。。。(PCA principal component analysis c code and principle document.)

estimate shape of a noisy image from the shading information

说明：  另外一种有效的椭圆陪陪技术，对于亚像素边缘检测非常有用的，真的不错(Oval to chat with another kind of effective techniques for sub-pixel edge detection is very useful, really good)
