摘要

PROBLEM TO BE SOLVED: To realize an object area description method by which the area of a desired object in a picture is described in a smaller data volume and its generation and data handling are facilitated. ;SOLUTION: In this object area information description method where information related to the area of an arbitrary object in the picture is described over a plurality of consecutive frames, an area 201 of the object in the picture is specified by at least one of an approximate figure 202 of the area of this object and characteristic points, and a locus obtained by arranging the positional data of representative points 203 of the approximate figure 202 or of characteristic points in accordance with advance of frames 200 is approximated by a prescribed function 204, and the parameter 205 of this function is used to describe information related to the area of this object.;COPYRIGHT: (C)2000,JPO
