Amelio :

The SetUpperThreshold and SetLowerThreshold methods replace the SetThreshold
method in the filter. This Canny filter performs iterative hysteresis
thresholding of the weighted zero crossing map as the final step in edge
detection. This requires two thresholds. The deprecated way was to specify
one threshold and the second was a hardcoded factor of the first. The new
way allows you to independently specify both thresholds.
