Abstract
Most computer vision systems use one-dimensional operators to calculate the curvature of boundaries or image contours. However, the more sophisticated biological systems use two-dimensional operators. Here we analyze how curvature can be computed by using two-dimensional operators and show the relation of this approach to the one-dimensional methods currently in use.
