+Digital geometry is a recent research domain where new mathematical definitions

+to better fit to the discrete nature of most of todays data to process.
+In particular, the notion of blurred segment \cite{DebledAl05,Buzer07} was

+with optimal width and orientation in gray-level images for as well

 We seek for user-friendly solutions with ideally no parameter to set,
 or at least quite few values with intuitive meaning to an end user.
 
-\subsection{Method overview and previous work}
+\subsection{Previous work}
 
-The method we propose is based on a first rough detection in a local area
+In a former paper \cite{KerautretEven09}, we already introduced an efficient
+tool to detect blurred segments of fixed width in gray-level images. 
+It is based on a first rough detection in a local area
 of the image either defined by the user in supervised context or blindly
 explored in automatic mode. The goal is to disclose the presence of an edge.
 Therefore, a simple test as the gradient maximal value is performed.
 
 In case of success, refinement steps are run through an exploration of
 the image in the direction of the detected edge.
-In order to prevent local disturbances, for instance the intersection with
-a sharper edge, all the local gradient maxima are successively tested,
-and the gradient orientation consistency is checked.
+In order to prevent local disturbances such as the presence of a sharper
+edge nearby, all the local gradient maxima are successively tested
+untill a correct candidate with an acceptable gradient orientation is found.
+
+Only the gradient information is processed as it provides a good information
+on the image dynamics, and hence the presence of edges.
+Trials to also use the intensity signal were made though costly correlation
+techniques, but they were mostly successful for detecting objects with
+stable appearance such as metallic pipes \cite{AubryAl17}.
 
-We already designed and experimented an exploratory detector
-\cite{KerautretEven09}.
+Despite of good performances obtained compared to other methods from the
+literature, several drawbacks remain.
+First, the blurred segment width is not measured, but initially set by the
+user to meet the application requirements, so that no quality information
+can be derived from the computed segment.
+Moreover, the blurred segment hull is left free to shift sidewards, or worst,
+to rotate around a thin edge in the image, so that the produced orientation
+value can be largely biased.
 
-Despite of good performances obtained compared
-to other methods from the literature, several drawbacks remained.
-At first, a fixed width value was set by the user according to the
-application requirements, and detected segments were embedded in that
-fixed tolerence whatever their dispersion be. When this dispersion is low,
-the blurred segment is free to shiff sidewards, or worst, to rotate, thus
-degrading the provided position and rotation measures.
+Then, two refinement steps are systematically run to cope with most of the
+tested data, although this is useless when the first detection is successfull.
+Beyond, there is no guarantee that this could treat all kinds of data.
+The search direction is fixed by the detected direction at the former step,
+and there is necessarily a limit on this direction accuracy - at least
+linked to the restricted directions encoded in a limited grid - so that
+other steps would have been necessary to deal with high resolution images.
 
-Then two refinement steps were arbitrarily run to cope with most of
-the tested data, uselessly when the first one was successfull.
-Beyond, there was no guarantee that this could treat all kinds
-of data. The search direction is fixed by the detected direction at the
-former step, and there is necessarily a limit on this direction
-accuracy - at least linked to the restricted directions encoded

-to deal with high resolution images.
+\subsection{Main contritions}
 
-Our study relies only on the use of the image gradient, as it provides a
-good information on the signal dynamics, and hence the presence of edges.
-Trials were made to use also the intensity signal though expensive
-correlation techniques, but it was mostly successful for tracking objects
-with stable appearance such as metallic pipes \cite{AubryAl17}.
+The work presented in this paper aims at solving both former mentioned
+drawbacks through two main contributions:
+the concept of adaptive directional scanner designed to get some compliance
+to the unpredictable orientation problem;
+the control of the assigned width to the blurred segment recognition algorithm,
+intended to derive more reliable information on the edge orientation and
+quality.
+As a side effect, this two major evolutions led to a noticeable improvement
+of the execution time.
 
-Organisation of the paper : TO WRITE.
+In the next section, the main theoretical notions this work relies on are
+introduced, with a specific focus on the new concept of adaptive directional
+scanner.
+Then the new detector workflow and its integration into both supervised and
+unsupervised contexts are presented and discussed in \RefSec{sec:method}.
+Experiments led to assess the expected increase of performance are decribed
+in \RefSec{sec:expe}.
+Finally achieved results are summarized in \RefSec{sec:conclusion},
+followed by some open perspectives for future works.
