10.34. Neighbor Orientation Comparison (Bad Data)
Group (Subgroup)
Orientation Analysis (Cleanup)
Description
This filter will calculate the misorientation between a cell and its 6 face neighbor cells if the Mask value is true of the target cell. If the misorientation falls below the user defined threshold for the user defined minimum number of neighbors, then the target cell will have its Mask value changed from false to true.
The filter will iteratively reduce the required number of neighbors from 6 until it reaches the user defined number. So, if the user selects a required number of neighbors of 4, then the filter will run with a required number of neighbors of 6, then 5, then 4 before finishing.
Warning - Data Modification
Only the Mask value defining the cell as good or bad is changed. No other cell level array is modified.

From the above before and after images you can see that this filter can help modify a mask that was generated through a simple threshold filter. This filter essentially uses neighbors to determine if a cell point should have had a mask value of false. The majority of cells that were changed from false or the black voxels, into valid IPF colored voxels, had a confidence index that fell just below the initial threshold applied (Confidence Index > 0.1 and Image Quality > 120). This filter determines that enough of that cell’s neighbors had a mask value of true, the misorientation was < 5 degrees and the cell had enough valid neighbors that the cell’s mask value was changed from false to true.
