some kinds of frequency interpolations.which are used to processing frequency and IFFT to image spce to new image

基于肤色和Hausdorff距离的人脸检测系统的matlab程序(Hausdorff distance based on skin color and face detection system matlab program)

说明：  运行主函数qam.m，可得到调用理论误符号率曲线和仿真结果。仿真结果包括误符号率和误码率。(running qam.m main function will receive the symbols mistakenly called theoretical curve and simulation results. Simulation results include misuse of the symbol rate and bit error rate.)

实现图像的傅里叶高通、低通滤波.经Fourier变换后的图像，中间部分是低频部分，外边是图像的高频部分。经过低通滤波后，图像中的高频成分被滤除掉，只留下低频成分，图像的边缘部分变得比较模糊了(useful for image Fourier high-pass, low pass filter)

产生雷达发射信号，相位编码采用巴克码，画出其调制信号的时域图和频谱图(barker code of radar . draw the graphic in time domain. draw the graphic in frequency domain.)

RFID ALOHA算法仿真，包括固定帧时隙、动态帧时隙和随机时隙算法(RFID ALOHA algorithm simulation, comprising a fixed frame time slot, time slot and frame dynamic random Slot Algorithm)

本程序是求解神经电另一chay方程的较为简单的例子。还有一个非线性物理中的Lorenz模型。可以帮助大家了解神经放电的问题()

利用FFT变换，对sine2进行频谱分析，画出频谱图 利用iir源程序对输入波形sine2进行低通滤波，并将结果输出至result.dat。 (Using FFT transform, spectral analysis of sine2, draw the spectrum graph use the input waveform iir source sine2 to low-pass filtering, and the results output to result.dat.)

说明：  这是最短路径动态规划问题及其程序设计，大家可以参考(hao)
