"WebCanny edge detection is accomplished using the edge function. Matlab will get "automatic/adaptive" thresholds if you don't specify thresholds as an argument. An easy way to implement this is to simply call Edge twice; first to get an initial capture of the thresholds, then to adjust thresholds as needed based on the automatic thresholds.
