Today's high speed computers, large and inexpensive memory devices and high definition displays have opened up the area of electronic image processing. Computers are being used to compress,enhance,and geometrically correct a wide range of image related data. It is necessary to develop Image Quality Merit Factors (IOW) that can be used to evaluate, compare, and specify imaging systems. A meaningful IQMF will have to include both the effects of the transfer function of the system and the noise introduced by the system. Most of the methods used to date have utilized linear system techniques to describe performance. In our work on the IOMF, we have found that it may be necessary to imitate the eye-brain combination in order to best describe the performance of an imaging system. This paper presents the idea that understanding the organization of and the rivalry between visual mechanisms may lead to new ways of considering photographic and electronic system image quality and the loss in image quality due to grain, halftones, and pixel noise.
