matlab小波变换源代码，供广大研究者学习(matlab wavelet transform source code, for the majority of researchers to learn)

说明：  小波变换的条件限制的实现的编程，可以更好设计优化问题(wavelet transform constraints on the realization of the program, we can better design optimization problems)

商图像 减少光照影响 可用于人脸识别的图像预处理(Business image recognition can be used to reduce illumination of the image preprocessing)

用FFT计算信号的功率谱密度时，需要先计算FFT，再计算双边谱密度，然后计算单边谱密度。在matlab里注意FFt要除以采样点数，计算双边谱时要注意除以频率分辨率。 ( When calculated using the FFT power spectrum density signal, you need to calculate the FFT, and then calculate the bilateral spectral density, and then calculate the unilateral spectral density. In matlab in Note FFt divided by sampling points should be noted when calculating the bilateral spectrum divided by the frequency resolution.)
