Description: 通过分析硬阈值函数的数学特性，并考察其对电能质量扰动信号的去噪过程可知，
该算法仅简单的对小波系数进行剔除与保留，在抑制噪声的同时也容易将突变点去除，
最终导致扰动定位失效，不利于分析电网故障的类型以及发生的起止时刻。(By analyzing the mathematical characteristics of the hard threshold function and investigating its denoising process to the power quality disturbance signal, it is known that the hard threshold function can be used to denoise the power quality disturbance signal.
The algorithm only removes and preserves the wavelet coefficients simply, and it is easy to remove the mutation points while suppressing the noise.
Finally, the disturbance location failure is not conducive to the analysis of the type of grid failure and the starting and ending time.)

Description: 非局部均值（NL-means）是近年来提出的一项新型的去噪技术。该方法充分利用了图像中的冗余信息，在去噪的同时能最大程度地保持图像的细节特征。基本思想是：当前像素的估计值由图像中与它具有相似邻域结构的像素加权平均得到。(NL-means is a new denoise method. It utilized image's information, preserving detail while denoise.)
