Abstract: The Harmonic Tracking Equalizer (HTEq) is an apparatus for and method of carrying out harmonic tracking equalization processing of an electrical signal, and apparatuses for and methods of controlling such equalization processing of the signal to dynamically sense the time-varying spectrum of an input signal and closely match a user desired audio signal spectrum while preserving the original dynamic range of the signal. The harmonically (sub-harmonically) tracked equalization is according to a user specified spectral request specified by a control interface that allows a user to request an amount of equalization to be applied to the signal. This apparatus is intended to process audio signals; though, it has general application to waveforms of other source and higher frequency content.

Abstract: The present invention is a target tracking system for enhanced target identification, target acquisition and track performance that is significantly superior over other methods. Specifically, the target tracking system incorporates an intelligent Tunable Wavelet Target Extraction Preprocessor (TWTEP). The TWTEP, which defines target characteristics in the presence of noise and clutter, 1) enhances and augments the target within the video scene to provide a better tracking source for the externally provided Track Process, 2) implements a tunable target definition from the video image to provide a highly resolved target delineation and selection, 3) utilizes a weighted pseudo-covariance technique to define target area for shape determination, extraction, 4) implements a target definition and extraction process, and 5) defines methodologies for presentation of filtered video and images for external processing.
