Wavelet Analyzer

Analyze signals and images using wavelets

Some tools currently available in waveletAnalyzer will be removed in a future release. For a list of those tools and recommend alternatives, see Compatibility Considerations.


The Wavelet Analyzer app 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

  • Denoise and compress signals and images

  • Design custom wavelets

  • Estimate density and regression

  • Perform matching pursuit analysis

  • Perform image fusion

Open the Wavelet Analyzer App

  • MATLAB® Toolstrip: On the Apps tab, under Signal Processing and Communications, click the app icon.

  • MATLAB command prompt: Enter waveletAnalyzer
