说明：  基于梯度直方图和支持向量机（HOG+SVM）的图像四分类matlab代码(HOG+SVM use for image classfication)

：以系统仿真软件MATLAB中的Sin-mlink软件包为工具，完成了通信系统中超外差接收机的动态仿真，并得到了完整的 仿真结果，总结出了利用Sitmdink进行动态仿真的基本方法和步骤。(: A system simulation software in the MATLAB software package for the Sin-mlink tools, completed a communication system in the dynamic simulation superheterodyne receiver, and a complete simulation results, summed up the use of dynamic simulation Sitmdink basic methods and steps.)

a modified method for polynomial regression is described in a very simple matlab program. easy to understand

Steganography project source code in matlab..

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.
