HIERARCHICAL FACE OBJECT SEARCH METHOD AND FACE RECOGNITION METHOD USING THE SAME HIERARCHICAL FACE OBJECT SEARCH SYSTEM AND FACE RECOGNITION SYSTEM USING THE SAME

摘要

A hierarchical face object search method is disclosed. The hierarchical face object search method includes the steps of: a) dividing a wide angle image acquired through a wide angle camera into one or more divided regions based on a zoom level of a PTZ camera; b) detecting an object in the divided region; c) searching for the object by the PTZ camera using the zoom level in which the object is detected and obtaining an object image about the object; and d) performing a face search using the object image. Accordingly, the present invention can improve an object search speed.
