Low / High threshold

浮點數

Set low and high threshold values used by the algorithm. The High threshold selects the 「strong」 edge pixels, which are then connected through 8-connectivity with the 「weak」 edge pixels selected by the Low threshold. Range is from 0.000 to 1.000 with Low threshold being lower or equal to High threshold.
