lifting_97
本程序实现任意偶数大小图像第二代双正交97提升小波变换
注1: 采用标准正交方法,对行列采用不同矩阵(和matlab里不同)
注2: 为了保证正交,所有边界处理,全部采用循环处理
注3: 正交性验证,将单位阵带入函数,输出仍是单位阵(matlab不具有此性质)
注4: 此程序是矩阵实现,所以图像水平分量和垂直分量估计被交换位置
注5: 此程序实现的是类小波(wavelet-like)变换,是介于小波包变换与小波变换之间的变换
注6: 此程序每层变换相对原图像矩阵,产生的矩阵都是正交阵,这和小波包一致
注7: 但小波变换每层产生的矩阵,是相对每个待分解子块的正交矩阵,而不是原图像的正交矩阵
注8: 且小波变换产生的正交矩阵维数,随分解层数2分减少
注9: 提升系数可以在MATLAB7.0以上版本,用liftwave( 9.7 )获取,这里直接给出,考虑兼容性
注10:由于MATLAB数组下标从1开始,所以注意奇偶序列的变化
注11:d为对偶上升,即预测;p为原上升,即更新(err)

Shape-Recognition
這是一個可以自動尋找图像中的長方形, 正方形, 圓形, 菱形的程式(1- Read the RGB (colored) image in from user.
2- Convert image from (RGB) colored to gray image.
3- Threshold the image (convert gray image to binary image).
4- Invert the binary image (in order to speed up the time of processing).
5- Find the boundaries concentrate.
6- Determine shapes properties (ratio of dimensions, roundness).
7- Classify shapes according to its properties. )

说明: 利用BP神经网络设计指纹识别算法,给神经网络提供每一模式类中的一些样本作为训练样本。BP网络经过学习,不仅能够识别已训练过的样本,而且能够识别未出现过的样本。利用神经网络的泛化能力,提高指纹识别算法的识别率,图像增强、提取指纹特征(BP neural network is the first mock exam to design fingerprint recognition algorithm, and it provides samples for each neural network as training samples. After learning, BP network can not only recognize the trained samples, but also recognize the samples that have not appeared. The generalization ability of neural network is used to improve the recognition rate of fingerprint recognition algorithm, image enhancement and fingerprint feature extraction)

mmread
mmread reads virtually any media file. If Windows Media Play can play
it, so should mmread. It uses the Window s DirectX infrastructure to
% render the media, so other OSs are out of luck.(mmread reads virtually any media file. If W for Windows Media Player can play it. so should mmread. It uses the DirectX in Window s GE% to render the media, so other OSs are out of luck.)
