在复杂背景下面，如何识别交通标志。。。。。。(Traffic sign recognition is a difficult task if we aim at detecting and recognizing signs in images captured from unfavorable environments.)

汉宁窗设计的FIR滤波器用于语音滤波，代码直接运行即可(Hanning window FIR filter designed for voice filtering, the code is run directly can)

说明：  该代码实现了频谱感知中的能量检测方法，对于能量检测的认识能有更深入的了解(The code implements the energy spectrum sensing in detection methods, knowledge of the energy detection can have a better understanding of)

for using this code need to use signal toolbox and general toolbox in your matlab Using Daubechies transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Daubechies transform and finding the SNR to see how well decompression works

Mammogram Enhancement

这是matlab编写的Logistic Discrimination 和 KNN分类器代码。这两个算法的实现参考了《Introduction to Machine Learning》。 除此在代码中还包含了调用matlab自带的libsvm的例程。rumLogisticDiscrimination， runKnn， runSvm分别对这3个算法在数据集liver_train_data上的分类准确度进行测试。测试结果在code report.doc 中有简要描述。(This code implements the Logistic Discrimination and KNN classifier. The implementation is according to the text book <<Introduction to Machine Learning>>. We have also compared the classification accuracy among Logistic Discrimination, KNN and SVM on data set liver_train_data. A brief test report is included as well. Enjoy :).)

目标因子分析,用于找主因子数，由例子能清晰明了的理解(Target factor analysis, the number of factors used to find the Lord, by the example of clarity of understanding can)

CARTOON Image abstraction using bilateral filtering. This function uses the bilateral filter to abstract an image following the method outlined in: Holger Winnemoller, Sven C. Olsen, and Bruce Gooch. Real-Time Video Abstraction. In Proceedings of ACM SIGGRAPH, 2006.

用s函数编写的异步电机的仿真模型，与模块搭建的相比，该模型简单可靠，不易出错(S function is written using the simulation model of induction motor, compared with the module structure of the model is simple and reliable, less prone to errors)
