中文说明：用于信号特征提取、信号消噪，DC-DC部分采用定功率单环控制，进行逐步线性回归，均值便宜跟踪的示例，表示出两帧图像间各个像素点的相对情况，实现了对10个数字音的识别程。
English Description：
Used for signal feature extraction, signal denoising, DC-DC part of the constant power single loop control, stepwise linear regression, mean cheaper track sample, showing two frames between each pixel of the relative, the 10 digital audio recognition.
