The demo of the Level Set method

说明：  一个基于dct变换的数字水印算法的源程序(A dct-based Digital Watermarking Algorithm source code)

本例利用小波分析检测信号中的奇异点并消除(Using wavelet analysis of signal singularity detection and elimination in)

this is for the use of the

此算法是基于matlab的MFCC特征提取算法，其中包括了分帧、归一化等步骤和代码，非常好用，结果是24维的向量(This algorithm is based on MFCC feature extraction algorithm matlab, including the framing, normalization and other steps and code, very easy to use, the result is 24-dimensional vector)

convolution filter application

buck电路的matlab仿真，单环控制(matlab simulink of buck circuit)

说明：  针对NL-Mreans算法运算时间较长的问题，提出了优化，大大缩短了时间。(To solve the problem of long operation time of NL-Means algorithm, an optimization method is proposed, which greatly shortens the time.)

进行滤波的算法，可用来设计滤波器，或者进行数字信号处理(Filtering algorithm can be used to design filters, or digital signal processing)
