Abstract
A demand for the dynamic range of input images in the binary subtracte d joint transform correlator was studied by computer simulations using input scenes containing multiple halftone images of human faces. To r ealize good discriminability the correlator requires use of an image-c onversion subsystem with a dynamic range larger than 50:1 and 16:1 in amplitude for input scenes having (1) a reference image and many targe t images and (2) a target image and many reference images, respectivel y.
