ABSTRACT:
A user gives, as input, two curves at a start time and at an end time and reference correspondence points with respect to the respective curves. Then, a pursuit operation of pursuing a reference correspondence point is carried out with respect to picture images successive in the time axis direction. As a result, positions of reference correspondence points at respective intermediate stages can be determined. Then, interpolation of the shape is carried out. Then, the determined interpolated shape is deformed in correspondence with the determined reference correspondence point. Accordingly, even in the case where a contour shape does not linearly move, it is possible to precisely pursue correspondence points on the contour. Thus, a contour shape with higher precision can be prepared.
