摘要：
Measuring audience size for a digital sign comprises generating a plurality of paths, one for each face detected in a first sequence of video frames captured by a camera proximate the digital sign, and generating a zone in the sequence of video frames through which passes a threshold number of the paths. Motion and direction of motion within the zone is then measured in a second sequence of video frames to calculate the audience size that passes through the zone in the second sequence of video frames.
