Contourlet

Wavelet-based contourlet packet using 3 dyadic wavelet levels and 8 directions at the finest level.

Contourlets form a multiresolution directional tight frame designed to efficiently approximate images made of smooth regions separated by smooth boundaries. The Contourlet transform has a fast implementation based on a Laplacian Pyramid decomposition followed by directional filterbanks applied on each bandpass subband.
