Counting passers-by using a color camera

摘要

We propose that passers-by be accurately counted using continuously acquired images from a color camera. This generates space-time images from image data on slanted measurement among images where a shadow component is removed via colorinformation. Passers-by are counted by counting groups of people distributed in space-time images, and the direction of movement is detected from the form of groups. Counting is actually done with a color camera on a gate.
