Title: Uneven structure matching method for closed curve
Inventor: UEDA SHUKO
IPC: G06T7/60
Filed: 1989-03-10
Abstract: PURPOSE:To hierarchically describe the uneven structure of the closed curve smoothed in stages by satisfying zero-crossing point corresponding restrictions. CONSTITUTION:By a convoluting operation with a Gauss function having a different dispersion sigma, the closed curve is smoothed in stages, and a curvature at each point on the smoothed curve for each obtained dispersion sigma is operated, and the zero-crossing point of the curvature is obtained. Next, out of the zero- crossing point set at each obtained dispersion sigma, the zero-crossing points are made to correspond so as to satisfy the zero-crossing point corresponding restrictions and so as to minimize the relaxation of the quota between the corresponding zero-crossing points. Thus the zero-crossing points can be made to correspond for the closed curve group between continuous scales, the incre ment of sigma is made larger, and the uneven structure of the closed curve group smoothed by the phased scale can be hierarchicaly described.
