Abstract: A method, system, and computer program for automatic restoration of digital film and video frames, by operation of a sequence of five main interactive computer program blocks, mainly separating moving objects from still objects, separating smooth texture from regions containing edges using the coherency map, and detecting and removing defects to provide restored frames using a pair of frames as reference frames for each processed frame.

Abstract: A method and system for automatic recognition and classification of a vibrating target among members of a plurality of objects having their vibration spectra stored in a database. In deciding as to which member of an alleged couple of vibrating objects the target should be assigned, the method uses an algorithm of signal processing which is based on wavelet packet analysis to predict a-priory a bandwidth in which the differences between the vibration of the spectrum is mostly pronounced, and the resolution within the bandwidth which is adequate to enable the decision.

Abstract: A method and apparatus for tracking a target. A signal from the target is received using a directional antenna and is digitized to provide a time series of samples. The samples are transformed, preferably by a wavelet transform. A signature of the target is identified in some of the transformed samples and a direction to the target is determined from others of the transformed samples. Target identification and target direction determination are iterated, with the identification being based on the most recently determined direction, and with the direction determination being based on the most recent identification, until a termination criterion is satisfied. Using wavelet transforms gives the antenna an effective beamwidth twenty percent narrower than the antenna aperture.
