利用Hough变换检测抛物线的算法。利用标准Hough变换从二值（黑白）图像中检测抛物线。(The use of parabolic Hough transform detection algorithms. Standard Hough transform from the binary (black and white) image in the detection of a parabola.)

*****将picture内的所有文件拷贝到MATLAB7.1软件下的名为word的子文件夹下********** 1.testpipei_1.m文件为基于灰度的模板匹配代码，仅为单独使用，不具有交互性 2.testpipei_2.m文件为基于灰度的快速模板匹配代码，仅为单独使用，不具有交互性 3.three.m为带有界面的演示程序，包含了上述两种算法，在MATLAB7.1中，在命令窗口下输入 edit three （three文件一定要在work文件夹下）回车后就可以进行使用了。 4.testpipei_1.m和testpipei_2.m的函数使用说明详细见各自的文件内 5.testpipei_1.m,testpiei_2.m,getOrder.m,gettezheng.m都为函数文件 three.m和three.fig共同为演示界面文件。 (Using MATLAB to image matching two images)

matlab实现灰度预测，很好的例子，有详细说明(Matlab to achieve grayscale prediction, a good example, with detailed instructions)

压缩文件是CNN卷积神经网络图像处理的数据库mnist_uint8.mat(Compressed file is the database of CNN convolution neural network image processing mnist_uint8.mat)

基于W-SVD的小波数字水印算法，包括水印生成、水印嵌入和水印检测，理解SVD奇异值分解算法。(Wavelet digital watermarking algorithm based on W-SVD includes watermarking generation, watermarking embedding and watermarking detection, and understanding SVD singular value decomposition algorithm.)

用于Landsat5 TM数据的辐射定标(Calibration for Landsat TM data using IDL)

数字图像处理的非常面全的图片，包含有各种格式的和大小的。(there are many kids of images that used to digitial image pricessing,including lena,boat,cman images)

说明：  按照最邻近原则把待分类样本点分到各个簇。然后按平均法重新计算各个簇的质心，从而确定新的簇心。一直迭代，直到簇心的移动距离小于某个给定的值。(According to the nearest neighbor principle, the sample points to be classified are divided into clusters. Then the centroid of each cluster is recalculated according to the average method to determine the new cluster center. Iterate until the moving distance of the cluster center is less than a given value)

实现手机拍摄图像的二维码图像的提取，包括QR码的旋转与校正，也可以用于其他条码，但是效果不是很好(The realization of mobile dimensional code image captured image extraction, rotation and including a QR code correction can also be used for other bar code, but the effect is not very good)
