Abstract
It is an object of the present invention to provide a method for automatically segmenting image objects by applying contour tracking to image objects with segmentation information of previous image object, and according to an aspect of the present invention, there is provided a method for segmenting an image object of a moving picture including the steps of: extracting and storing a contour of a previous image object of a previous scene by using a predetermined segmentation information of the previous image object; calculating a motion information by extracting a contour of the previous image object at a current scene; extracting a contour of a current image object by using the motion information and a space domain information of previous and current scenes; and extracting an image object area of the current image object at the current scene by using the contour of the current image object.
