[波变换] WAVE-weifengyin

小波变换具有多分辨率分析的特点,并且在时频两域都具有表征信号局部特征的能力。小波变换通过将时间系列分解到时间频率域内,从而得出时间系列的显著的波动模式,即周期变化动态,以及周期变化动态的时间格局(Torrence and Compo, 1998)。小波(Wavelet),即小区域的波,是一种特殊的、长度有限,平均值为零的波形。它有两个特点:一是“小”,二是具有正负交替的“波动性”,即直流分量为零。小波分析是时间(空间)频率的局部化分析,它通过伸缩平移运算对信号(函数)逐步进行多尺度细化,能自动适应时频信号分析的要求,可聚焦到信号的任意细节。

[波变换] WaveletFusion

基于小波变换的多传感器融合算法,先通过小波变换分离低频信号和高频噪声,计算高频噪声的方差,通过不同传感器信号噪声方差的大小决定不同传感器的置信程度(方差越小,权重越大),最后进行信号融合。
Wavelet-based multi-sensor fusion algorithm, the first separation of low-frequency signal by wavelet transform and high frequency noise, calculate the variance of high frequency noise, the noise variance by different size of the sensor signals of different sensors determine the degree of confidence (the smaller the variance, the greater the weight ), and finally for signal integration.

[波变换] xiaobofenxijiangyi

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。与Fourier变换相比,小波变换是时间(空间)频率的局部化分析,它通过伸缩平移运算对信号(函数)逐步进行多尺度细化,最终达到高频处时间细分,低频处频率细分,能自动适应时频信号分析的要求,从而可聚焦到信号的任意细节,解决了Fourier变换的困难问题,成为继Fourier变换以来在科学方法上的重大突破。有人把小波变换称为“数学显微镜”。 这套讲义生动详实的快速带领初学者掌握小波的基本要点,是不可多得的好材料!
