image brightness threshholding and contrasting from gonzalves book of digital image processing

这个程序是幅值谱中校正频谱峰值的比值校正法，可以自设定校正谱峰值的个数，比值校正法还可以校正相位，校正的结果很准确(This procedure is correction of the amplitude spectrum of the ratio of the peak spectrum correction method, correction can be set from the number of spectral peaks, the ratio correction method can also be correction phase, the results of very accurate correction)
