摘要： In an object region data generating method for moving picture, an object region is approximated with a polygon in each frame (S11). Each vertex of the polygon in one frame is associated with each vertex of the polygon in adjacent frame based on the distance between the vertexes (S12). A trajectory of the vertex is obtained on a time-series variation of the associated vertexes (S13). The object region data is generated based on the trajectory of the vertex.
