Abstract
A model for image perception is described in which the percept is first constructed from visual primitives and then deconstructed into diagnostic features that are suitable for symbolic manipulation. The relationship of the model to the psychophysics of medical imaging is discussed in terms of the relationship between image appearance and the observer response. Some methods for modifying the image to aid visual perception are discussed. They include image enhancement, computer image analysis, and feedback assisted visual search. Some of the perceptual aspects of the search component of the detection-location task are described. Finally, the implications of the model are presented for those who would assist image perception or utilize visual feature extraction.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
