利用小波熵自适应去噪并求出各层熵值（绝对值表示） 及权重，自写论文(Using wavelet entropy adaptive de-noising and the obtained layers entropy (absolute value) and weight, since writing papers)

这是新提出来的用于图像去噪的非局部均值滤波方法, matlab程序.非常好,你试试.(this is a new proposed image denoising method--non local means filtering, matlab file. you can try!)

双数复小波变换及其图像去噪算法。。。。。(Double the number of complex wavelet transform and image denoising algorithm. . . .)

相当的经典啊 是基于MATLAB的 大家做图像匹配的都可以用的到(Fairly classic MATLAB-ah is based on the U.S. to do image matching can be used to)

　　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.)

RGB颜色空间转换为 YCbCr 和HSV空间，自己编写的matlab 代码，希望对打家有帮助。(RGB color space is converted to YCbCr and HSV space, have written matlab code, want to combatants spar in home help.)

一个交互式程序，利用Hough变换检测圆。允许人工选择圆半径。(An interactive process, the use of Hough transform circle detection. Permit artificial selection radius.)

显示图像灰度，可以鼠标点击显示的起始位置及设置显示区域的大小(show the gray of picture ,can click the position and set the scales)

使用MFC以及Gabor小波处理进行图像的特征纹理提取(Using MFC and Gabor wavelet to extract texture features for image)
