Abstract
A distortion-invariant joint transform correlator based on the concepts
of the fringe-adjusted joint transform correlator and the synthetic
discriminant function is presented. Computer-simulation results show that the
proposed joint transform correlator is distortion-invariant for the target
image from the training set and produces sharper correlation peaks and lower
sidelobes compared with the classical joint transform
correlator.
