An Interactive Digital System For Image Enhancement And Restoration
P. Krause · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1984
Photographs are sometimes degraded by various defects which make it difficult or even impossible for a human observer to extract the relevant information from the picture. Examples of degradations are: low contrast, perspective distortions, blur due to defocusing , camera or object motion, and atmospheric turbulence. To improve the image quality in the presence of these degradations an interactive digital image enhancement and restoration system has been set up in hardware and software.
