ABSTRACT:
An improved grid moving method of an object image and an apparatus using the same which are capable of reducing the amount of information with respect to the image of an object by moving the grid in accordance with a position in which an image of the object having shape information exists, which include the steps of: a moving step for forming a grid over an image of an object having shape information, segmenting the image into a plurality of unit regions, and moving the formed grid; a judging step for judging an amount of the information at each position to which the grid is moved in the moving step; a detecting step for detecting a position at which the amount of the information is reduced; a compaction step for reforming the grid in accordance with the position detected in the detecting step and for coding the image of the object existing in unit regions of the reformed grid; and a motion estimation step for reforming the grid in accordance with the position detected in the detecting step and for estimating the motion of the image of the object in the unit regions in which the image of the object exists among the unit regions segmented by the reformed grid.
