This paper introduces a new straight thick edge detector in gray-level images
based on blurred segments, digital objects able to embed quality measurements
on the extracted features. This study enhances previous works on interactive
line detection with a better estimation of the blurred 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 detection of all the segments in a single image
is also proposed and left available in an online demonstration.
