Automatic Object Measurement - Condition
The measurement conditions are used to limit the objects to be evaluated (e.g. only objects with defined
minimum value). All objects are tested against the defined conditions. If the conditions are fulfilled the
feature values are written to the data table.
Fig. 7-39
To define the following parameter select the Condition tab sheet of the Automatic Object
Measurement dialog window.
The list on the very left at the dialog shows all the measurement Features . The second list provides the
comparison Operators and the next Numbers to define a value. This gives the possibility to compose an
expression to test a feature value against a constant value. The fields above the lists will show the
composed (selected) string. Clicking on the desired list entry does the selection. The button with the
„>>„ characters adds this string to the
List of Conditions . All lines of the List of conditions are
combined with the AND expression automatically. To remove a condition line double-click on it.
The parameter Minimum Volume defines the minimum voxel volume for the measurement. This is an
easy way to eliminate very small regions caused by noisy sequences and segmentation process.
The button Remove All will clear the list of defined conditions.
Clicking on the Apply button will execute the measurement process and switch to the General tab sheet
of the dialog.
Parameters:
Feature List of available object features
Operator List of available condition operators
Number List of numbers to compose the value
List of conditions Defined condition list
Remove All Remove all entries from the List of conditions
Minimum Volume Minimum object volume in voxel
