这个程序是粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。且已经过调试(This program is a particle swarm optimization procedures, using Matlab implementation is very simple. Only a few dozen lines of code. And has been commissioning)

带色彩恢复的多尺度视网膜增强算法（MSRCR）的原理、实现及应用。 (Multi-scale recovery of the retina with color enhancement algorithms (MSRCR) principle, implementation and applications.)

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.

Support for wireless communication: MIMO

关于支持向量机的很好的学习材料，附有一个基于matlab条件下的小程序。(Support vector machine on a good learning materials, with a little under matlab-based program.)

Range-Free Localization Schemes for Large Scale

pwm没有做SVPWM，而仅仅是单极性PWM。PI参数调试的不是很好，可能调制波波形不太好(pwm did not do SVPWM, while the Unipolar the PWM. PI parameters debug not very good, may be modulated waveform is not very good)

Linear convolution between two sequences

matlab实现单尺度retinex算法，实现图像增强。(matlab achieve a single scale retinex algorithms for image enhancement.)
