第3个：matlab 和C++联合用于SLSVM，另外一种风格的(the 3file: matlab and c++ together for SVM)

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程序，实现广义S变换功能，广义S变换是用于时频分析的一重算法。(ST code in matlab)

中值滤波窗口大小影响滤波器性能,3×3滤波窗口可以很好地保持图像细节。提出一种新的自适应中值滤波方法。将3×3窗口中心的极值点作为候选噪声点,若候选噪声点仍然是7×7窗口的极值点,则该点即是噪声点。若以噪声点为中心的3×3滤波窗口的中值不是噪声,则噪声用中值替换。重复以上过程,直到没有噪声点被替换。(Median filter window size affect the filter performance, 33 filter window can be well preserving image detail. Propose a new adaptive median filtering method. The 33 extreme point of the center of the window as the candidate noise the candidate noise is still 77 extreme points of the window, the point is that the noise point. Terms of noise centered on the point 33 filtering window value is not a noise, the noise is replaced with the median. The process is repeated until there is no noise point is replaced.)

本文具体介绍了有关投影法进行字符分割的程序源码(This article describes the specific projection method for character segmentation procedure source)

在OFDM系统 中，宽带信道被分割相互重叠的窄带子信道，如果各子信道 的带宽比信道的相干带宽要小，那么信号传输就有可能在无 频率选择性衰落或者平坦衰落的信道进行。(In OFDM system The wideband channel is divided into narrowband sub-overlapping, if each sub- The bandwidth is less than the coherence bandwidth of the channel, the signal transmission is possible without Frequency selective fading or flat fading channels.)
