  This paper introduces a fully discrete framework for a new straight line
detector in gray-level images,
where line segments are enriched with a thickness parameter
intended to provide a quality criterion on the extracted feature.
This study enhances previous works on interactive
line detection with a better estimation of the segment width and
orientation through two main improvements: adaptive directional scans and
the control of the assigned width to the detection algorithm.
A new contribution to the automatic detection of all the segments in a single
image is also proposed and left available in an online demonstration.
