Hi! I am making a leaf vein. I got two results from the similar graphs. Does anybody know why do these results differ?

 

Settings: 2 Edge Detect graphs have the same settings. The Blend graph has Copy blend mode and 100% opacity.SDEdgeDetectIssue.jpg

I'll check your sbs file later when I'm back in the office but from glancing  at your screenshots the inputs are different to those edge detect nodes. One is being fed a 16 bit image, the other an 8 bit image which is more likely to have stepping in the gradient. Dave
