Abstract :
A mathematical model representing certain aspects of how the eye processes pictures is given. The emphasis in modeling is on how the eye adapts to changes in signal intensity, signal-to-noise ratio, and bandwidth. A few comparisons are made between the computed results of the model and of the psychophysical measurements to assess the limitations of artificial pattern recognition systems.
