| 发明名称 | Object counter and method for counting objects | ||
| 摘要 | An object counter performs a method for estimating the number of objects crossing a counting boundary. The method comprising: capturing, during a time period, a plurality of images representing moving images; registering, from the captured images, motion region areas passing across the counting boundary; calculating the integral of the registered motion region areas for forming a resulting total motion region area; and estimating the number of objects that have crossed the counting boundary by dividing the resulting total motion region area by a reference area. | ||

| 主权项 | 1. A method for estimating the number of objects crossing a counting boundary, the method comprising: capturing, during a time period, a plurality of images representing moving images; registering, from the captured images, motion region areas passing across the counting boundary; calculating the integral of the registered motion region areas for forming a resulting total motion region area, wherein calculating the integral of the registered motion region area comprises summing area slices of motion regions from a plurality of the captured images; and estimating the number of objects that have crossed the counting boundary by dividing the resulting total motion region area by a reference area. | ||
