Introduction

Digital Image processing basics using matlab and can be transformed to c++ using open cv

说明：  一个学习bp算法的MATLAB源代码，仅作学习交流之用(A learning algorithm bp MATLAB source code used only for study and exchange)

图论算法，包括弗洛伊德最短路径算法以及最短路径算法，最小生成树算法(Graph algorithms, including shortest path algorithm and the Floyd shortest path algorithm, minimum spanning tree algorithm)

i need code for matlab

Feature Extraction from EEG

分段异常信号实验，几个不同频率的信号叠加用HHT方法进行分解，是我做实验用的信号，验证无误，(Abnormal signal sub-experiment, several different frequency signal superimposed with the HHT method of decomposition, I did experiment with the signal, verify the correct)

利用matlab实现svm函数包的调用，在人脸数据库yale上进行人脸识别(using matlab to apply function svm to achive scan face on the data of yale )

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

matlab实用程序百例源码，非常适合matlab初学者(matlab utility hundred cases of source, very suitable for beginners matlab)

说明：  Matlab中非小波工具箱的应用小波变换处理图像，可以copy，cut，paste小波分量。(Matlab toolbox to the Central African Wavelet Transform Image processing can copy, cut, paste wavelet weight.)
