This correspondence describes a moving target tracking (MTT) algorithm that performs image registration and motion analysis between pairs of images from a passive sensor. Unlike previously reported moving target indicators that operate at the signal level, the registration and motion analysis in the MTT is totally performed at a symbolic level. The(More)
Coherent optical systems are well known for performing certain operations such as Fourier and Fresnel transformation and pattern recognition. The basis for pattern recognition in many coherent optical systems is the correlator. This paper discusses the effect of undersampling in an optical joint transform correlator which has a sampled-data input, detectors(More)
OBJECTIVE Ensuring the transmurality of the mitral isthmus lesion, a critical component of the cryomaze, entails mirror-image application of the cryoprobe both on endocardial and epicardial surfaces when carrying out ablation. Concerns of circumflex artery injury have been expressed during the epicardial application of the cryoprobe over the coronary sinus(More)
