支票印鉴图的R、G、B三个分量的显示图像并将RGB图转换为灰度图像(Check seal map R, G, B three components of the display image was converted to grayscale and RGB images)

对信号进行小波变换，得到小波系数和逼近系数，求出各个频率段的能量（能量=小波系数的平方和(wavelet transform)

说明：  lms消噪 语音降噪，自适应滤波算法，进行改进，误差调节三个参数(LMS denoising, speech denoising, adaptive filtering algorithm, improved, error adjustment of three parameters)

基于MVDR算法，计算两个信号的相关性的函数。(This program computes the coherence function between 2 signals x1 and x2 with the MVDR method. This algorithm is based on the paper by the same authors: J. Benesty, J. Chen, and Y. Huang, "A generalized MVDR spectrum," IEEE Signal Processing letters, vol. 12, pp. 827-830, Dec. 2005. x1, first signal vector of length n x2, second signal vector of length n L is the length of MVDR filter or window length K is the resolution (the higher K, the better the resolution))
