Gripper Clearance Tool Display Window The Display window shows the image being processed, the region of interest selected, and the locations of found instances. The elapsed time is displayed at the bottom of this window. Grid of Results Instances that satisfy all histograms will be reported as results. The Position X, Position Y, and Position Angle are the same for this tool as they are for the Relative To tool (the input to this tool). Areas outside the region of interest are considered solid, so parts near the edge may not be returned as instances if a histogram goes off the region of interest.

Elapsed Time is not displayed in the grid of results, but is shown at the bottom of the Display window for each iter- ation of the Image Histogram Tool. Instance Index of the result instance. Position X X coordinate of the origin of the instance. Position Y Y coordinate of the origin of the instance. Position Angle Angle of the instance. Grey Level Mean n, Mean greylevel for each histogram n, reported for each result instance Histogram Pixel Count n Number of pixels from Threshold Black to Threshold White, inclusive, in histogram n.
Variance n Variance of greylevel values from the mean in his- togram n.
