US 8,798,327 B2 · Method and system for people flow statistics

Abstract

A method and system for people flow statistics is disclosed in the invention, wherein said method comprises: multi-types of classifiers connected in parallel are used to perform the human head detection in the current image, the respective human heads in the current image are determined; the respective determined human heads are tracked to form the human head target movement tracks; and the people flow is counted at the direction of the human head target movement track. It can be seen, a plurality of classifiers connected in parallel are used in the invention, multi-types of human head targets, such as dark colored hair, light colored hair and caps of various colors, and the like, can be detected simultaneously.
