Abstract
A method and apparatus including a camera collecting video images of a secured area, extracting objects; for each extracted object determining an object size, correcting the object size, for each extracted object determining, an object size, an object aspect ratio, an object speed and object motion path track, comparing the distance corrected object size with a statistical bell curve tuned to nominal human size, comparing aspect ratio to a statistical bell curve tuned to nominal aspect ratio of human proportions, comparing object speed to a statistical bell curve tuned to nominal travel speed of a typical human and comparing object motion path track against ramp function of absolute distance traveled over time, determining a respective threat probability for each of the extracted object signatures based upon the corrected object size, summing the respective threat probabilities and generating an motion alert upon detecting the summed threat probabilities exceeding a threshold value.
