Webb28 feb. 2014 · The fully automatic, image-based delineation of individual stones of built heritage can be very challenging, due to the characteristics of the objects to be delineated and the environment in which they are. Stone masonry walls of built heritage are built with many types of stones and mortar. Webb8 jan. 2013 · Probabilistic Hough Transform is an optimization of the Hough Transform we saw. It doesn't take all the points into consideration. Instead, it takes only a random subset of points which is sufficient for line detection. Just we have to decrease the threshold.
