小波变换 [xiǎo bō biàn huàn]
WT (Wavelet Transform)
- 近年来，一种被称为小波变换的数学理论和方法成为众多学科关注的焦点。
Recently, a new mathematical technique known as wavelet transform (WT) has become the focus of many science areas. - 仿真结果表明，这种算法不仅比传统基于小波变换的各种滤波算法有更高的PSNR值，而且能更好地保持图像细节。
The experimental results demonstrate that the new denoising algorithm substantially surpasses those based on wavelet transforms, both visually and in terms of PSNR. - 小波变换在电力系统的故障信号处理中得到广泛地应用，然而，小波变换只能消除白色噪声，对有色噪声不起作用。
Although wavelet transforms(WTs) are being used to process fault signals of power system widely. Wavelet transforms can only filter white noises and are useless to filter colored noises.
