| Abstract(in English) | In this paper, we define digital curvature flow for spatial digital objects. We first define the principle normal vector for each point on the digital bounday of a spatial object. Digital curvature flow is defined as motion of boundary according to this principle normal vector on each point. Therefore, digital curvature flow is a digital version of curvature flow. Furthermore, this flow which moves the boundary could also be considered as discrete curvature flow on an iso-polyhedron, all edges of which are parallel to the axes of an orthogonal coordinate system. Our treatment of curvature flow is also considered as a numerical method for partial differential equation of curvature flow in a grid space. |
