%0 Book Section %T Digitally generated soft edges with predetermined luminance: An analysis of its influence on image degradation. publisher SPIE--The International Society for Optical Engineering %D 1998 %U 0-8194-2793-4 %@ https://hdl.handle.net/20.500.14352/60834 %X The presence of degraded or soft edges on a scene or digital image may cause ambiguities in depth perception(1,2). This kind of edges has been analyzed by introducing a mathematical model to digitally implement a large category of degraded edges. This model has accounted the origin of degradation, the performance of psychophysical test for measuring the degradation perception, and image characteristics currently used in artificial vision as momenta, number of gray scale level per pixels, etc. It is the subject of current researches to be applied to artificial reproduction of human visual perception. %~
