<P>PROBLEM TO BE SOLVED: To efficiently recognize an object that appears halfway in an animation. <P>SOLUTION: White areas within animation object image frames Fdy 1-Fdy last stored in a moving object image memory 9 are extracted. A temporary label characteristic of each white area is imparted, with the temporary label of the first animation object image frame Fdy 1 serving as the main label. As (i) is started from 2, the white area of the animation object image frame Fdy (i-1) that best matches the white area of the animation object image frame Fdy i in pattern is retrieved. When the retrieval was successful, the value of the main label imparted to the retrieved white area of the animation object image frame Fdy (i-1) is given to the white area of the animation object image frame Fdy i as the main label and both of the white areas are related with each other for the same object. When the retrieval is unsuccessful, the temporary label for the white label of the animation object image frame Fdy i is rewritten with the main label of a new value. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
