註釋Abstract: "In this paper we describe a new method for identifying groups of intensity edges in an image. The method groups together edges that are likely to result from the same convex object in the scene. A key property of the method is that its output is no more complex than the original image. In contrast, existing methods may produce many more groups than there are edges in the image (e.g., finding pairs of parallel segments may result in a quadratic number of groups). Our method first uses a triangulation of the image edges to define a local neighborhood that is scale invariant.
