Stationary partitions in 2D nonstationary processes: nondyadic anisotropic Malvar's decomposition and two-dimensional spectral distance tree

Abstract

In this article, we propose a simple algorithm allowing the research of stationary partitions in locally stationary 2D processes, by use of adapted local bases like the local 2D DCT. The algorithm aims at finding some windows of which width is adapted to the rate of change in the 2D spectrum. For this, we define an anistropic Malvar's decomposition with a… (More)
