\b Example:
-Détection of the cost line on a nautical chart
+Detection of the cost line on a nautical chart
\image html contour_detection_example2.png
-To use the <b>Shape recogition</b> tool you have to \ref import_picture_page "Import a picture" in the view first.Then you can choose to create either <b>contours</b> or <b>corners</b> out from this picture.
+To use the <b>Shape recogition</b> tool:
+
+<ol>
+ <li>\ref import_picture_page "Import a picture" in the view</li>
+
+ <li> Select <b>New Entity -> Shape Recognition</b> or click on \image html feature_detect.png </li>
+
+</ol>
+
+
+
+Then you can choose to create either <b>contours</b> or <b>corners</b> out from this picture.
+
+\n
To create <b>Contours</b> :
<li> Find a zone in the picture which color is representative of the zone you want to find the frontier of. Draw a rectangle on it to take a <b>Snapshot</b>.</li>
<li> Apply </li>
+
+ The \b Result will be a \b Compound of \b Edges or \b Wires from which you can explode the desired edges or wires.
+
+ \image html feature_detection_dlg.png
+
+ <b> Output type </b> :
+
+ <ul>
+
+ <li> \b Spline : each contour will be a single \b edge based on a B-Spline curve</li>
+
+ <li> \b Polyline : each contour will be a wire made of lines (i.e. a \b Polygon)</li>
+
+ </ul>
+
+ \note It's better to use the \b Spline output type unless you want to find the frontier of a polygon (rectangle ...)
+
</ol>
+\n
+
+To create <b>Corners</b> :
+
+<ol>
+ <li> In the <b>Picture</b> field select a previously imported picture.</li>
+
+ <li> Apply </li>
+
+ The \b Result will be a \b Compound of \b Vertices
