Abstract
In this paper we describe a new antialiasing technique for discrete re gions. We propose the use of a new model of contours, called euclidean paths, which provides an approximation of the underlying real boundar y of a discrete region. Euclidean paths are used to compute the blendi ng coefficients of the frontier pixels. This method allows us to super impose a discrete region on a background while avoiding the well-known staircase effect.
