Abstract
Current imaging display systems are capable of digitizing an image to eight bits of gray scale (256 levels). For demanding imaging applications such as X-ray images or satellite images more levels of gray scale may be required to extract fine details in the complex images. Obviously the digitization process should not result in the loss of critical information. Conversely the extension of gray scale capability beyond eight bits is associated with a marked increase in system expense and development resources. The desire, then, is to provide all the visual information that the human observer is capable of detecting without over-designing the system beyond the capacity of human vision.
