Paper Abstract

An improved fringe-adjusted joint transform correlation (FJTC) technique is proposed, which employs a new real-valued filter, called the logarithmic fringe-adjusted filter. The Fourier-plane image subtraction technique is applied to the joint power spectrum before applying the inverse Fourier transform to generate better correlation output. The proposed technique yields better correlation output compared to alternate optical pattern recognition techniques when the target is embedded in noise-corrupted input scenes. Test results are presented to verify the performance of the proposed technique.
