Neighbor Orientation Correlation¶
This Filter first identifies all Cells that have a confidence index below the minimum set by the user. Then, for each of those Cells, their neighboring Cells are checked to determine the number of neighbor Cells with orientations different than the reference Cell by more than the user defined misorientation tolerance. In addition the neighboring Cells are compared with each other to determine the number of neighboring Cells that have the same orientation (again within the user defined tolerance). The Cleanup Level set by the user is then used to determine which Cells are replaced. If a level of 5 is set, then at least 5 of the neighboring Cells must be different than the reference Cell and at least 5 of the neighboring Cells must be the same as each other (and so on for other Cleanup Level). If a Cell meets the replacement criteria, then all of its attributes are replaced with the attributes of one of the neighboring Cells that are the same as each other.
Note: The Filter will iteratively reduce the Cleanup Level from 6 until it reaches the user defined number. So, if the user selects a level of 4, then the Filter will run with a level of 6, then 5, then 4 before finishing.
Neighbors are defined as a the "nearest neighbors" which share a "face". For 3D structures it is 6 neighbors that share a common face with the current cell.

Schematic layout of the neighboring cells. Only the In-Plane neighbors are shown.
In this example cell (1,1) has a confidence index < 0.1 and the surrounding cells all have a misorientation tolerance not greater than 5 degrees. Comparing cell (1,1) with its neighbor cells we can see that the misorientation is greater than 5 Degrees. In this case the central cell (1,1) would have all of its attributes replaced with the "best" neighbor based on the phase of a neighbor cell matching the central cell.
|Minimum Confidence Index||float||Sets the minimum value of 'confidence' a Cell must have|
|Misorientation Tolerance (Degrees)||Float||Angular tolerance used to compare with neighboring Cells|
|Cleanup Level||int32_t||Minimum number of neighbor Cells that must have orientations within above tolerace to allow Cell to be changed|
