Abstract
A method for counting a number of people includes detecting a foreground contour from a current frame inputted, performing a head detection by defining a baseline virtually at a point perpendicular to a center point of a camera-captured area, by defining a search area around the baseline, and by detecting, as as candidate heads, circular contours to be recognized as heads of people at a point where the foreground contour crosses the baseline, tracking the candidate heads respectively in subsequent frames until the candidate heads pass through the search area, and counting up the number of people by the candidate heads that respectively pass through the search area.
