Design and analysis of real-time detection system for small targets moving

Temporal recursive low-pass filtering algorithm and multi-frame correlation were presented to detect samll moving targets in complicated background. A real-time implementation hardware system was designed, which fits to backg round varying slowly or stationary with respect to the environment. Target and its region location were determined precisely with the condition of con stant false alarm probability. Contours of small targers were identified wi th adaptive threshold.
