Wavelet Explorer is a Mathematica application package that provides wavelet analysis capabilities useful for an extraordinary array of applications including signal and image processing and data analysis. With Wavelet Explorer, you can:
Generate commonly used filters such as the Daubechies' extremal phase and least asymmetric filters, coiflets, and spline filters
Visualize wavelets and wavelet packets and zoom in on their details.
Transform your data to a host of wavelet bases, wavelet packet bases, or local trigonometric bases and do inverse transforms in one and two dimensions.
Perform data compression and denoising
In addition, Wavelet Explorer is an excellent interactive tutorial for those who are new to wavelet theory.
