Dl. Flannery, OPTIMAL TRADE-OFF DISTORTION-TOLERANT CONSTRAINED-MODULATION CORRELATION FILTERS, Journal of the Optical Society of America. A, Optics, image science,and vision., 12(1), 1995, pp. 66-72
A closed-form filter formulation that builds on the optimal trade-off
filter formulation and uses the minimum-Euclidean-distance principle i
s presented. This new formulation provides filters that are optimal in
a mean-square error sense relative to multiple criteria over a traini
ng set of images when they are implemented with limited modulation lev
els typically afforded by spatial light modulators. The relationship o
f the new formulation to several existing filter concepts is discussed
