发明名称 Apparatus and method employing pre-ATR-based real-time compression and video frame segmentation
摘要 One subject of this invention is the development of a novel region of interest (ROI) method, or Frame Segmentation Method that can be provided within a video stream, in real-time, or more precisely within a few milliseconds of video frame duration of 30 msec, or even in the sub-millisecond range. This video frame segmentation is the basis of Pre-ATR-based Ultra-Real-Time (PATURT) video compression. Still other subjects of this invention are morphing compression, and watermarking, also based on the PATURT. The applications of the PATURT innovation include ROI-based real-time video recording that has special applications for aircraft pilot/cockpit video recording in “black-box” devices, recording aircraft accidents, or catastrophes. Such black-box devices usually need to pass high impact (3400 g), high temperature (1100° C., in 1 h), and other harsh environmental tests. In this invention, they also have the capability of reporting the last cockpit events up to 0.5 seconds before an accident, including all cockpit sensor readings, as well as pilots' behavior, the latter with fully scrambled and non-recoverable facial information. Further applications include video surveillance. The latter can be also applied to missile defense (recognizing real target or real missile, from false targets (decoys)), or to other Ultra-Real-Time (URT) civilian and military scenarios.

主权项 1. A method of determining an object contour in an image frame of a video employed in a video processing system, the method comprising: determining a phase space representation of the image frame; selecting a phase space filter from a set of phase space filters according to an estimated size of the object, wherein the set of phase space filters comprises phase space filters having a plurality of different phase space scale responses; scaling the phase space representation using the selected phase space filter; discarding redundant points of the scaled phase space representation to form a filtered frame; comparing the filtered frame with a reference frame to determine an approximate object contour; and storing the approximate object contour on a computer readable medium.
