+\section{Experimental validation}
+
+The evaluation stage aims at quantifying the advantages of the new detector
+compared to the former one.
+For a fair comparison, the process flow of the former method (the initial
+detection followed by two refinement steps) was coded as an option of the
+new detector, because since that time, the code of basic routineshas
+largely been improved.
+For instance, the new directional scanners are encoded as an iterator so that
+only required scan lines are provided when required, whereas with the former
+code, all the scan lines were computed and returned, whenever they were used
+or not.
+We just checked that the outputs of the new coding of the former detector
+are equivalent to those of the old release.

+The former detector do not estimate the edge width, but just circumscribes

+If the edge is very thin, the blurred segment is free to rotate around the
+extracted edge and the provided orientation is biased.
+Moreover it lets some space to incorporate additional spurious outliers.
+With the new appoach, a real estimation of the edge width is provided.
+The main risk of outlier incorporation remains at the beginning of the
+blurred segment expansion as long as the minimal width continues to grow
+and the assigned width has not been set to the detected segment minimal width.
