Pyramids in digital imaging
Rimon Elias · The International Conference on Electrical Engineering/The International Conference on Electrical Engineering · 2008
This article surveys important concepts related to pyramidal architecture, hierarchicalprocessing and multi-resolution techniques in imaging context. Types of processesincluding bottom-up and top-down related to such hierarchical structures are explained.Relationships consisting of intra-level and inter-level communication networks arediscussed. We investigate regular and irregular pyramidal structures. This includes binpyramid;quad-pyramid (and overlapped quad-pyramid); dual-pyramid; hexagonalpyramid;adaptive pyramid and disparity pyramid.
