wishlist:completed:add_non-maximal_suppression_and_hysteresis_to_the_canny_edge_algorithm

Add non-maximal suppression and hysteresis to the Canny edge algorithm

The algorithm needs to surpress non-maxima perpendicular to the edge direction.

Thomas Boudier has kindly produced an edge detection plugin based on Canny-Deriche filtering. The non-maximal suppression and hysteresis are described here. This allows to reduce the edges to binary elements.

Some code is available here: http://www.cs.ucf.edu/~mikel/Research/Edge_Detection.htm

  Done!
