Threshold Objects

Group (Subgroup)

Processing (Threshold)

Description

This Filter allows the user to input single or multiple criteria for thresholding Attribute Arrays in an Attribute Matrix. Internally, the algorithm creates the output boolean arrays for each comparison that the user creates. Then all the output arrays are compared and if any of the values for a specific Object is false, the corresponding Object in the final output array is marked as false. This is considered a logical "or" operation. An example of this Filter's use would be after EBSD data is read into DREAM.3D and the user wants to have DREAM.3D consider Cells that the user considers good. The user would insert this Filter and select the criteria that makes a Cell good. All arrays must come from the same Attribute Matrix in order for the Filter to execute. For example, an integer array contains the values 1, 2, 3, 4, 5. For a comparison value of 3 and the comparison operator greater than, the boolean threshold array produced will contain false, false, false, true, true.
