22 August 1988Highly Multiplexed Optical Correlation Filters
Composite filters constructed with synthetic discriminant function algebra and binary phase-only Fourier transforms of training images are demonstrated through digital simulation. These are shown to provide high multiplicity and S/N, with unusually low scatter in S/N parameters compared to filters constructed with input plane images.
