Abstract
This study offers a three-dimensional motion compensation system that is effective when the moving body is a polyhedron. Features of this system are the introduction of a borderline extraction method which extracts only the contour of a pattern-bearing solid, as well as the extraction of the information on surface disappearance and appearance which uses frame-to-frame changes in the vertex position. Detected three-dimensional motion information has also been used to achieve accurate synthesis of a moving-body image.
