A quality metric for an arbitrary 2D edge contour is presented. This metric is constructed from measured physical characteristics of the edge. It enables a comparison of performance of different edge detecting algorithms and provides a tool for the optimization of edge detectors. The metric was verified using the Canny’s edge detector applied to a set of artificial images varying in image quality.
