Multi-Scale Salience Distance Transforms

By Paul L. Rosin and Geoff A. W. West


The distance transform has been proposed for use in computer vision for a number of applications such as matching and skeletonisation. This paper proposes two things: (1) a multi-scale distance transform to overcome the need to choose edge thresholds and scale and (2) the addition of various saliency factors such as edge strength, length and curvature to the basic distance transform to improve its effectiveness. Results are presented for applications of matching and snake fitting.
