Abstract : An autonomous real-time adaptive video target detection and position location apparatus and method. Adaptive low pass filters produce horizontal leading and trailing edge and vertical thresholds from each frame of input target and a background or clutter video signal. A user selectable input is used with the three adaptive thresholds, input video, and horizontal synchronization signal to produce a signal representing valid target detection and position information.
