Abstract

A system and method for detecting anomalies in a video. The system comprises a digital image input to receive a plurality of frames. Each frame has a plurality of pixels each corresponding to a pixel location in each of the frames. The system uses a background model based on spatio-temporal filter responses at each pixel location in the frame and an anomalous motion detector to generate a score for each pixel based on the background model at the pixel location. The score is compared with a threshold score indicative of a maximum score for the pixel location to fit the background model. An anomalous motion signaling system triggers an anomalous motion signal when the comparison of the score for at least one pixel with the threshold score indicates that the spatio-temporal filter responses at that pixel location differ sufficiently from the background model.
