Detection of object boundaries is an important step in the analysis of an image. In the presence of a textured background, local edge operators generate many edges that do not correspond to the object boundaries. However, edges along the object boundaries link in elongated segments. An efficient algorithm to perform such linking is described and experimental results of a working program are presented.
