用MATLAB实现人体检测的特征提取，效果不错，需要简单的修改(Human Detection Using MATLAB implementation of feature extraction, good results, require simple changes)

Intermodulation or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with nonlinearities. The intermodulation between each frequency component will form additional signals at frequencies that are not just at harmonic frequencies (integer multiples) of either, but also at the sum and difference frequencies of the original frequencies and at multiples of those sum and difference frequencies.
