DEMO_WAVELETFILTERS - Invertible wavelet filter banks via grid-like sampling

Description

This demo shows how to generate invertible wavelet filter banks.

The following wavelet filter banks are produced:

demo_waveletfilters_1.png

Non-uniformly sampled wavelet filter bank

The figure shows a non-uniformly sampled invertible filter bank with conventional, geometric frequency spacing.

Non-uniformly sampled wavelet filter bank

The figure shows a non-uniformly sampled invertible filter bank with geometric frequency spacing, a higher redundancy and using a wavelet with different Q-factor.

Uniformly sampled wavelet filter bank

The figure shows a uniformly sampled invertible filter bank with geometric frequency spacing, where the scales are passed directly as input arguments.

Uniformly sampled wavelet filter bank

The figure shows a uniformly sampled invertible filter bank with linear frequency spacing where the compensation channel index is passed directly. invertibility is achieved by passing a small delay to the filter generator.

The figure shows a comparison of the filter center frequency spacing.
