Low-entropy image pyramids for efficient lossless coding and progressive transmission
David Houlding, Jacques Vaisey · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1994
An efficient image source coding technique gives good compression performance at low computational complexity. This research introduces an efficient coding technique, based on pyramid coding, that involves transforming an image into an equivalent, lower entropy form prior to lossless coding. The proposed method is also a multiresolution technique that facilitates progressive image transmission.
