Detecting primitive events at checkout

摘要

Techniques for detecting one or more events are provided. The techniques include identifying one or more segments in a video sequence as one or more candidates for one or more events by a temporal ordering of the one or more candidates, and analyzing one or more motion patterns of the one or more candidates to detect the one or more events.

主权项

1. A method for detecting one or more events, comprising:
generating a motion graph from a video sequence captured at a point-of-sale (POS) system, the motion graph representing human motion in the video sequence; detecting two consecutive scan events at the POS system by identifying a first reference motion pattern in the motion graph; identifying a segment of the video sequence between the two consecutive scan events; and upon identifying the video sequence segment, analyzing a portion of the motion graph corresponding to the video sequence segment to detect at least one of a pick-up event and a drop event by identifying a second reference motion pattern in the motion graph.
