Paper Abstract

The performance of binary joint-transform correlation using realistic input scenes has been studied by simulations addressing the effects of variations in threshold level, low-frequency blocks, and spurious signals due to regularly spaced groups of multiple (identical) input targets. A design tradeoff between better correlation performance and easier implementation (higher thresholding levels) was observed for constant thresholding. A new adaptive thresholding technique is introduced which alleviates the problems encountered using constant thresholds and significantly improves performance. Results are given for input scenes consisting of challenging backgrounds with multiple targets.
