Wavelet Analyzer

Analyze signals and images using wavelets

Some tools currently available inwaveletAnalyzerwill be removed in a future release. For a list of those tools and recommended alternatives, seeCompatibility Considerations。

Description

TheWavelet Analyzerapp is an interactive tool for using wavelets to visualize and analyze signals and images. With the app, you can:

Perform wavelet and wavelet packet analysis
降噪、压缩和信号images
Estimate density and regression
Perform matching pursuit analysis
Perform image fusion

Open the Wavelet Analyzer App

Some tools in the Wavelet Analyzer app have been removed

The following tools in theWavelet Analyzerapp have been removed.

Tools	Replacement
Continuous Wavelet 1-D (Using FFT)	To take the CWT of a single time series, use`cwt`。 To take the CWT of multiple time series, the recommended procedure is to precompute a CWT filter bank with`cwtfilterbank`and apply the filter bank to multiple time series. SeeUsing CWT Filter Bank on Multiple Time Series。 To visualize the scalogram, use`cwt`。 To visualize wavelets in time and frequency, use`cwtfilterbank`。
New Wavelet for CWT	To tune the generalized Morse wavelet to your needs, vary the time-bandwidth and symmetry parameters of`cwtfilterbank`或`cwt`。 To create a custom DWT filter bank, use`dwtfilterbank`。看到Add Quadrature Mirror and Biorthogonal Wavelet Filters。
Fractional Brownian Generation 1-D	To synthesize fractional Brownian motion, use`wfbm`。
Wavelet Display,Wavelet Packet Display	To visualize the analytic Morse, Morlet, and bump wavelets in time and frequency, use`cwtfilterbank`。 To visualize orthogonal and biorthogonal wavelets in time and frequency, use`dwtfilterbank`。 To visualize in time other wavelets such as the Meyer, Morlet, Gaussian, Mexican hat, and Shannon wavelets, use`wavefun`。 To display wavelet packets, use`wpfun`。
Signal Extension,Image Extension	To extend real-valued vectors or matrices, use`wextend`。
