+these concepts. Such an result can not be compared to other approach since they do not provide any width estimation.
+Moreover the performance of the unsupervised mode give better coverage of the detected edges and produce quite comparable execution time.
 
 A residual weakness of the approach is the sensitivity to the initial
 conditions.
