Threshold
Adaptive Threshold
Adaptive Threshold adjusts the edge threshold on each acquired image. The Sensor automatically sets the threshold
and attempts to adjust for contrast variations.
Edge Strength
Edge Strength sets the edge threshold at a predetermined gray scale value from 0 to 127. Edge Strength provides more
control over what gets to be considered an edge pixel.
Edge Length
The tool ignores target patterns with edges equal to or shorter than the specified number of pixels for edge length.
Legend
All edges found by the Geometric Find tool are color-coded in the Image window. Strong edges show up in green, and
weak edges show up in red.
Note: Both weak and strong edges in the pattern ROI are expected to be present in the inspection.
