Method and apparatus for measuring audience size for a digital sign |
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. |

1. An apparatus to measure audience size for a digital sign, comprising:
a processor; a memory coupled to the processor; a face detection module including machine instructions that when loaded from memory and executed by the processor generate a plurality of paths, one for each face detected in a first sequence of video frames captured by a camera proximate the digital sign; a calibration module including machine instructions that when loaded from memory and executed by the processor generate a zone in the first sequence of video frames through which passes a threshold number of the paths; and a counter module including machine instructions that when loaded from memory and executed by the processor measure motion and direction of motion within the zone in a second sequence of video frames to calculate the audience size that passes through the zone in the second sequence of video frames. |
