ABSTRACT:
The invention provides a of simulating the performance of systems such as r-infrared imagers which must be described with shift variant spread functions and non white noise. Simple approximations are substituted for the spread functions and these are convolved with the pixel samples before and after the noise is added to produce a degraded but very realistic simulation of the video signal or other characteristic output of the system.
