小波变换去噪
- 小波变换去噪:小波(Wavelet)这一术语，顾名思义，“小波”就是小的波形。所谓“小”是指它具有衰减性；而称之为“波”则是指它的波动性，其振幅正负相间的震荡形式:(Wavelet (Wavelet) the term, as the name suggests, "wavelet" is a small waveform. The so-called "small" means that it has a decay; and called "

基于小波变换的图像降噪
- 基于小波变换的图像去噪，从含噪图像可以看出噪声含量非常强，而从去噪的结果可以看出，通过小波去噪后的图像基本和原图像一致。第一次消噪滤去了大部分高频噪声，但与原图比较，依然有不少高频噪声，第二次消噪在第一次消噪基础上，再次滤去高频噪声，消噪效果较好，但图像质量比原图稍差。(Image denoising based on wavelet transform shows that the noise content is very strong from noisy images, and from

Matlab小波去噪
- 小波重构的时候waverec(c,l,'db1');其中c和l都应该是列向量，所以将数个向量合并成c时最好分别将他们弄成行向量，合并后转置就成了列向量。(When the wavelet reconstruction is waverec (C, l,'db1'), C and l should all be column vectors, so when several vectors are merged into C, it is best to make them a row vecto
新的小波去噪程序
- 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
