Gripper Clearance Tool NOTE : The Inspection Configuration field ignores this property when using Grey Level Mean for filtering. Tails A tail specifies a percentage of pixels to be removed from the dark and light ends of the initial histogram. Tail Black Grey Level Value Tail Black Grey Level Value specifies the percentage of the total number of pixels in the his- togram to ignore at the dark end of the greylevel distribution in each histogram. After its cre- ation, the histogram is scanned, starting from greylevel 0. The pixels at the dark end of the histogram are then cleared until the percentage of pixels defined by Tail Black Grey Level Value is reached.
Tail White Grey Level Value Tail White Grey Level Value specifies the percentage of the total number of pixels in the his- togram to ignore at the light end of the greylevel distribution in each histogram. After its cre- ation, the histogram is scanned, starting from greylevel 255. The pixels at the light end of the histogram are then cleared until the percentage of pixels defined by Tail White Grey Level Value is reached. Custom Menu Offset Specifies the offset and rotation of the selected histogram from the tool origin. X, Y, Degrees. Search Region Specifies the height and width of the selected histogram. Add Adds a new histogram.
If this is not the first histogram in this tool, the previous histogram is replicated, with 0 rotation, and with X and Y values 20 greater than the previous histogram. Delete Removes the selected histogram. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 485
