FilterAnalysis
Filters objects from an analysis object.
Access to parameter description
For an introduction:
The input filter contains the criteria to preserve objects from the input label image. These criteria are defined by one or several analysis measurements ranges.
If the label image used to generate the input analysis had a coordinate system unit defined in its calibration property, the filter limit values and analysis results are expressed in this coordinate system unit.
