Amelio :<br><br>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.

Hi,<br><br>When running a program in which I call<br>itk::CannyEdgeDetectionImageFilter::SetTreshold() I get a warning<br>saying that the method was deprecated. However, I have not seen<br>anything at the ITK help website that indicates that the method is
<br>deprecated. Also, if SetThreshold is deprecated, how do I choose the<br>threshold to binarize the result? (Please note that<br>CannyEdgeDetectioImageFilter binarizes the output).</blockquote><div> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
