Shape List ROI
Type
Each Shape is separate ROI: Each shape is processed as a separate
ROI.
ShapeList is One ROI: The tool calculates average intensity as if there is
only one ROI, no matter how many ROIs are used. The tool averages all
the pixels from all the ROIs together and produces one Average Intensity
and one Passed result. The Average Intensity and Passed Lists are one
value long.
Tolerance Type Use Uniform Tolerance
Use Nominal Intensity List and +- tolerances
Use Tolerance List
Uniform Tolerance If Tolerance Type is Use Uniform Tolerance, this tolerance value is
applied to the average intensity of each of the ROIs.
Use this value when there is one ROI or all ROIs are expected to have
the same intensity.
Click Train to set this value to the overall average intensity of all the
ROIs.
The parameters are minus, nominal, and plus.
Nominal Intensity
List
If the Tolerance Type is Use Nominal Intensity List and +- tolerances, this
list of values is used as the Nominal Intensity value for each of the ROIs.
The Plus and Minus Tolerance values are applied to each Nominal value
in the list to set the allowed average intensity for each ROI.
Use this mode when each ROI is expected to have a different intensity,
but you want Plus and Minus Tolerances that apply to all ROIs, even as
you add them.
Click Train to recalculate the values in this list. If this property is linked,
training has no effect.
Plus Tolerance This value is used as the Plus tolerance for all the values in the Nominal
Intensity List and the initial Plus tolerance for the values in the Tolerance
List.
Minus Tolerance This value is used as the Minus tolerance for all the values in the Nomi-
nal Intensity List and the initial Minus tolerance for the values in the Tol-
erance List.
Tolerance List If the Tolerance Type is Use Tolerance List, this list of values, along with
the Plus Tolerance and Minus Tolerance values, is used as the Nominal
Intensity value for each of the ROIs.
Use this mode when you want to set the plus and minus tolerance of
each ROI separately.
Click Train to recalculate the nominal value of each tolerance in the list.
You must adjust the Plus and Minus Tolerance manually. If this property
is linked, training has no effect.
Number of ROIs
Allowed to Fail
If the number of ROIs that fail is greater than this value, the tool fails.
Intensity Offset This value is added to the Average Intensity Result for each ROI.
Enable Difference
List Out
If True, the Intensity Difference List is generated.
