Publisher's Synopsis
A method and apparatus for counting a number of persons in an image are provided. The person counting apparatus includes: a detector configured to detect a movement area in a top-view distance image, of at least one image frame, providing distance information; an estimator configured to estimate a candidate head area from the movement area based on the distance information; and a determiner configured to determine whether the candidate head area is an actual head of a person based on a similarity to a circle of the candidate head area and a spherical curvature of the candidate head area estimated from the distance information about the candidate head area.
