Abstract

The Wigner Distribution (WD) function produces a simultaneous space-spatial frequency description of an image and thus provides an appropriate domain for analyzing spatial non-uniformities in an image. In this paper, the performance of WD based processors is compared to that of the cross-correlator for a simple pattern recognition problem. A method is also proposed to reduce the computational complexity of the WD based system. Difference between digital WD based and optical WD based processors is pointed out.
