Adaptive or a priori filtering for detection of signals corrupted by noise |
摘要 |
A method for pattern recognition and localization using a joint transform correlator and joint transform correlator. The method includes providing a joint image of a reference image and an input scene image at the input plane of the correlator, receiving the joint image and providing a Fourier transform interference field of the reference image and the input scene image, receiving the Fourier transform interference field and providing a joint power spectrum, compensating for noise prevailing within the input scene image by processing the joint power spectrum to produce a noise compensated joint power spectrum, and receiving the noise compensated joint power spectrum and providing a noise tolerant correlation signal so as to enhance pattern recognition and localization capabilities.
