METHOD FOR DIVIDING MOVING VIDEO OBJECT BY TRACKING CONTOUR LINE

摘要

PROBLEM TO BE SOLVED: To provide a method capable of exactly dividing a video object with a little effort in a comparatively short time by dividing the video object through a method for tracking the contour line of the video object concerning the video object to appear later while utilizing the division information of the video object to appear on a video sequence. SOLUTION: This dividing method is provided with steps 301-302 for extracting the contour line of the preceding video object from the division information of the preceding video object in the preceding scene inputted from the outside and storing this contour line later, step 303 for calculating the motion information of the contour line of the preceding video object in the present scene and extracting the contour line of the present video object while utilizing the above motion information and the spatial area information of the preceding and present scenes, and step 304 for extracting the area of the present video object in the present scene while utilizing the contour line information of the present video object.
