PROJECT TITLE :

A New Contourlet Transform With Adaptive Directional Partitioning - 2017

ABSTRACT:

A new image sparse representation tool-adaptive contourlet transform (ACT) is introduced in this letter. Adaptive directional partitioning schemes in ACT can match the arbitrary orientation distribution of natural image, which brings sparser representation. The proposed ACT relies on pseudopolar Fourier remodel that has similar geometrical structure to fan filter. This characteristic helps ACT out of the problem of designing ancient directional filter bank. Simulation results demonstrate that ACT will give more efficient image sparse illustration compared to contourlet rework.
