Abstract:
Disclosed is a computer-implemented method for classifying a detected region of change of a video frame as indicating an abandoned object or a removed object, the detected region of change is classified as an removed object if the temporal change of the edge consistency is from a more consistent state to a less consistent state, and the detected region of change is classified as an abandoned object if the temporal change of the edge consistency if from a less consistent to a more consistent state.
