Abstract

Abstract:
This article surveys important concepts related to pyramidal architecture, hierarchical
processing and multi-resolution techniques in imaging context. Types of processes
including bottom-up and top-down related to such hierarchical structures are explained.
Relationships consisting of intra-level and inter-level communication networks are
discussed. We investigate regular and irregular pyramidal structures. This includes binpyramid;
quad-pyramid (and overlapped quad-pyramid); dual-pyramid; hexagonalpyramid;
adaptive pyramid and disparity pyramid.
