摘要： An animation solid is created by an animation solid generator such that the shape of its cross section at t=t0 coincides with the shape of the contour of an object contained in a frame to be displayed at t=t0, wherein time t is set in the height z direction of the solid. For creation of this solid, topological considerations, including connected components and the tree structure of contours, are used. By chopping this solid, intermediate dividing can be performed. The basis of the topological geometry rests on Morse theory.
摘要翻译：通过动画实体发生器创建动画实体，使得其在t = t0处的横截面的形状与包含在要在t = t0处显示的帧中的对象的轮廓的形状一致，其中时间t被设置在固体的高度z方向。为了创建这种实体，使用拓扑考虑，包括连接的组件和轮廓的树结构。通过切割这个固体，可以进行中间分割。拓扑几何的基础依赖于莫尔斯理论。

摘要： A multiresolutional filter called a critical point filter is introduced. This filter extracts a maximum, a minimum, and two types of saddle points of pixel intensity for every 2.times.2 (horizontal.times.vertical) pixels so that an image of a lower level of resolution is newly generated for every type of a critical point. Using this multiresolutional filter, a source image and a destination image are hierarchized, and source hierarchical images and destination hierarchical images are matched using image characteristics recognized through a filtering operation.

摘要： A topography information data processing system acquires ground surface data which represents bumps and hollows on the ground, generates manifold data which represents the shape of the manifold that encloses the bumps and hollows on the ground based on the ground surface data, and acquires topological geometric data applying the Morse theory to the manifold data. A new type of geographic information data representation is provided by using topological geometric data generated based on the Morse theory known in differential geometry and differential topology. Geographic information data suitable to be stored in a recording medium or to be transmitted through a network is provided.
