Abstract
An object counter performs a method for counting objects that includes capturing images representing moving images of a predetermined counting view, detecting a motion region in the moving images of the predetermined counting view, calculating a motion region speed value indicating a speed of movement of the motion region. A contribution zone is repeatedly defined based on a predetermined counting boundary, the motion region speed value, and a contribution time period. A sub area value representing the size of the area of the motion region contained in the defined contribution zone is repeatedly retrieved and registered. A total area value is generated by adding a plurality of registered sub area values, and estimating the number of objects that have passed the counting boundary based on a reference object area value.
