基于核函数回归方法的图像去噪，图像平滑。对于图像领域的研究者有很大作用(Kernel regression method based on image denoising, image smoothing. Researchers in the field for the image plays a significant role)

zxing相关的二维码开发类库的编译工具，最新版本的apache-ant-1.9.3(zxing related to the development of libraries of the two-dimensional code compilation tools, the latest version of apache-ant-1.9.3)

在MATLAB环境下实现了CDMA通信系统仿真，程序流程为：随机序列产生--WALSH码扩频--BPSK调制--加入（和不加入）高斯白噪声--BPSK解调--WALSH码解扩，对过程波形进行了存储，对加噪与不加噪情况下的解码结果进行了对比，并绘制出信噪比与误码率关系图。(In the MATLAB environment to achieve a CDMA communication system simulation, the program flow as follows: random sequence generated- WALSH yards Spread Spectrum- BPSK modulation- to join (and not to join) Gaussian white noise- BPSK demodulator- WALSH yards Solution expansion of the process of waveform storage, to add noise and without noise cases, the decoding results were compared, and draw out the signal to noise ratio and bit error rate diagram.)

用于场景分类的代码，特征是事先提取好的，用PHOG特征(For scene classification code, characterized in that prior extraction good PHOG characterized)
