Multiresolution imaging: information efficiency and visual quality
Rachel Alter-Gartenberg, Zia-ur Rahman · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
Multiresolution imaging consists of image gathering, signal decomposition, quantization and either reconstruction or restoration. Our assessment of this process for restoration, in terms of information and fidelity, integrates optical filtering in image gathering and display with digital filtering and decimation in signal decomposition. This approach establishes upper bounds on the information efficiency of the data transmission for images restored with the best possible visual quality.
