Edges Counting Tool - Settings Tab 

Defines the minimum acceptable edge contrast score for the found edge (1-100; default = a "Smart Setting" that is automatically decremented until an edge is detected). This setting determines the tool’s edge detection sensitivity - its ability to discriminate between the feature and the background; use this setting in conjunction with the tool’s Graph to set an acceptable range.

Defines the transition of the edge (Dark to Light, Light to Dark or Both; default = Both). For increased accuracy and speed, specify the type of transition.

Defines the pixel distance (1 - 50; default = 3) over which an edge transition takes place. This setting helps filter noise from the image.

Defines the maximum amount of angular translation that the found edge can experience (0-10°; default = 10°). The higher the allowable angle variance, the longer the tool will take to execute.
