Abstract:

The initial set of problems studied in this work consisted of 1 the comparison of the behaviour of photographic grain in coherent versus incoherent optical systems 2 a more complete understanding of the signal dependence of grain in coherent and incoherent systems and 3 the implications of the results of 1 and 2 in the fields of image evaluation and image processing.
