A method for detecting events in a video sequence includes providing a video sequence (200), sampling (201) the video sequence at regular intervals to form a series of snapshots of the sequence, measuring (202) a similarity of each snapshot, measuring a similarity change (203) between successive pairs of snapshots, wherein if a similarity change magnitude is greater than a predetermined threshold, a change event has been detected, verifying (204) the change event to exclude a false positive, and completing (205) the processing of the snapshot incorporating the verified change event. |
