An adaptive discrete contour smoothing
Abstract
This paper presents an original smoothing method for discrete contours containing different characteristics depending on the scale. The optimal scale is determined by a survey of the contours in terms of texture. An abstract can be then derived; it consists in the inflexion and dominant points of the discrete contour under study and in the directions of the tangents at these points. The smoothing computed starting from such abstract uses the theory of straight line envelopes. Neither threshold nor experimental parameter are required and the smoothing provides the underlying continuous feature of a discrete contour seen at a given scale.
