Next, we investigated CNs at different r-values in the range of 0.2 to 0.3 for the NI-CN and in the range of 0.4 to 0.5 for the REC-CN (Fig. 2).As before, the r threshold value was defined as the r-value when the minimum or maximum edge number was located outside … WebYour rectangle's minimum vertical side length is L m i n pixels. Your edge detection only finds 80% of each edge. Then the minimum threshold will be 0.8 L m i n You many need to modify this if, for example, your edges tend to be thicker or thinner than the 80% figure.
