Abstract

In this paper, we define digital curvature flow for spatial digital objects. We define the principal normal vectors for points on the digital boundary of a binary spatial object. We apply the discrete curvature flow for the skeletonisation of binary objects in a space, and develop a transform which yields the curve-skeletons of binary objects in a space.
