Difference in Job Mode

The available functionality of the individual steps can differ between the wizard in Free Mode and the steps that can be added in Job Mode, e.g. the Interactive checkbox is not visible in Job Mode.

In this step you select the measurement features.

Parameter		Description
Interactive		Activated: The features can be changed interactively while the analysis setting is run.
Class List		Selects the class for which you want to define measurement features. You can specify different settings for each class.
Features of Individual Regions/Features of All Regions		Displays the features for the currently selected class/all classes and allows you to select additional features.
–	Select	Opens the dialog for feature selection.
–	Copy to All	Copies the defined features to all other classes.
–	Feature	Displays the feature name(s) added for the currently selected class.
–	Display	If you activate Display in the feature selection dialog for a feature, the result of the measurement is displayed next to the corresponding object in the analyzed image. Deactivated: The measurement is performed but not displayed in the image. This prevents the image becoming cluttered.
Annotations		Allows you to add annotations to the image, for example to indicate areas of particular significance.
–	Select	Opens the dialog to select or edit the image annotations.
–	Copy to All	Copies the annotations to all other classes.

–	Name	Defines the name of the feature.
–	Unit	Specifies the unit of the feature as free text input. This input is optional.
Define Operands		Displays and defines the operands used for the calculation of the custom feature.
–	Operand	Displays the name of the operand.
–	Class	Selects the class that is used for the definition of the operand. For a single region class, also the classes of the children can be selected.
–	Feature	Displays all available predefined measurement features for the selected class and selects which measurement feature should be used for the definition of the current operand. If you activate the checkbox behind the selection dropdown, the selected feature is also set visible in the result table.
–	Expression	Displays the expression of the Operand(s) defined by the Class and Feature selection.
–	+ Add	Adds a new operand to the list.
–	Delete	Deletes the currently selected operand.
Define Custom Expression		Defines the mathematical calculation of the feature, using the Operands and mathematical operators, e.g. *100(a/b+Math.Pow(c,2))**.
–	+	Adds the mathematical operator for summation to the calculation.
–	-	Adds the mathematical operator for subtraction to the calculation.
–	*	Adds the mathematical operator for multiplication to the calculation.
–	/	Adds the mathematical operator for division to the calculation.
–	Pow	Adds the mathematical operator to calculate the power of a certain base value. Note that this operator requires two input values (the base and power value) separated by a comma, e.g. Math.Pow (2,3), which corresponds to 2³.
–	Sqrt	Adds the mathematical operator to calculate the square root of a value.
–	Abs	Adds the mathematical operator to return the absolute number, i.e. non negative values.
