P. Refregier et al., NONLINEAR JOINT-TRANSFORM CORRELATION - AN OPTIMAL SOLUTION FOR ADAPTIVE IMAGE DISCRIMINATION AND INPUT NOISE ROBUSTNESS, Optics letters, 19(6), 1994, pp. 405-407
We develop a processor for pattern recognition that is optimum in term
s of discrimination and is tolerant to variations of the object to be
recognized. This optimum processor is found to be adaptive nonlinear j
oint-transform correlator.
