Description: 局部放电试验所采集的信号中往往混有白噪声、周期干扰信号去除。此处采用常用db系列小波中的db6小波进行9尺度的多分辨分解后，根据白噪声能量特性，估算各尺度的阈值大小，采用硬值进行处理，后进行重构。-Partial discharge test of the signal collected is often mixed with white noise, periodic interference signal removal. Here the use of commonly used wavelet db Series DB6 wavelet carried out in the 9-scale multiresolution decomposition, based on the energy characteristics of white noise to estimate the scale threshold size, the use of hard-value deal, after the remodeling.

Description: 根据图像小波分解的特点和小波分解后高频小波系数的统计特性,构造了一种新阈值函数的去噪算法。
与传统的硬阈值、软阈值函数相比,新阈值函数考虑了图像能量分布的特点,对于每一小波系数乘以一个与自身大小相
关的降噪因子,并且新阈值函数简单易于计算,具有较强的自适应性-According to the characteristics of image wavelet decomposition and wavelet decomposition after the high-frequency statistical characteristics of wavelet coefficients, construct a new threshold function of the denoising algorithm. With the traditional hard threshold and soft threshold function, the new threshold function takes into account the characteristics of the image energy distribution, for each wavelet coefficient multiplied by a size associated with self-noise factor, and the new threshold function simple easy calculation, has a strong self-adaptability
