ABSTRACT:
A difference between an input image including images of a background image picked up by an image pick-up unit and an object to be monitored is produced as an image of the object, the image of the object is divided into a plurality of parts and the plurality of divided image of the object are produced as a plurality of templates. Each of the plurality of templates is matched with a new input image and images of a plurality of parts in the new input image which have highest degrees of matching with the plurality of templates are used to update the plurality of templates to output a plurality of new templates. Each of the plurality of new templates is matched with a further new input image and images of a plurality of parts in the further new input image which have highest degrees of matching with the plurality of new templates are used to update the plurality of new templates to output a plurality of further new templates. In this manner, the plurality of templates are sequentially updated for the new input images to trace the object.
