Patent 4674125 Issued on June 16, 1987. Estimated Expiration Date: June 16, 2004. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
Pipe-line architecture is employed for analyzing in delayed real time the frequency spectrum of an information component (having one or more dimensions) of a given temporal signal having a highest frequency of interest of no greater than f0, and/or for synthesizing in delayed real time such a temporal signal from the analyzed frequency spectrum thereof. Such pipe-line architecture is particularly suitable for image-processing the two-dimensional spatial frequencies of television images defined by a temporal video signal.
