Title: Tracking device and tracking method
Inventor: OTSU NOBUYUKI
IPC: G06V10/24
Filed: 2004-12-02
Abstract: <P>PROBLEM TO BE SOLVED: To provide a tracking device and a tracking method enabling the real-time tracking of a moving object such as a person from a dynamic image by a method with a small processing load, and enabling further accurate tracking by learning characteristics through the tracking.  <P>SOLUTION: In this tracking device, input dynamic image data are divided to partial images (reed shape or rectangular shape), and a divided image where a tracking object is present is extracted by comparing a present image with a background image containing no tracking object. Color high-order local self-correlation characteristic data enabling the extraction of characteristics of a color and a shape at once for the identification of the tracking object are calculated, and the identification is performed based on a distance from registered characteristic data of the tracking object. Further, the background data or registered characteristic data are updated to the latest ones. Since the characteristics are acquired while tracking the tracking object, and an object is identified by use of the characteristics, robust and accurate tracking is enabled.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
