Differences on Workflow Tab

For workflows, the Image Segmentation step and tool offer the controls of the wizard step Automatic Segmentation. However, the Interactive and Execute checkboxes are not available, as the workflow defines how the step is executed, see ZEN Workflows.

Additionally, you only have the possibility to select the Segmentation Method if you have started the workflow with Run to here for this step. In other workflow runs (automatic or stepwise), the method is taken from the setting loaded with the and Load Setting tool of the Image Analysis step at the beginning.

In this step you can select the segmentation method that is applied and set parameters for the segmentation of the objects that you want to measure. Note that during the setup of the analysis (via Edit Image Analysis Setting), the segmentation is only performed on the area visible in the viewport. If you enter the analysis wizard via Start Interactive Analysis, the image will be fully segmented.

Parameter

Description

Execute

Activated: Sets the defined threshold values when the measurement program is run.

Interactive

Activated: The segmentation can be changed interactively while the analysis setting is run with Start Interactive Analysis.

Class List

Selects the class for which you want to define the segmentation.

Ring Element Class

This additional parameter is only available if you have selected the Zone of Influence (ZOI) method.

-

Ring Distance

Distance from surface of the primary object. Negative values mean that the ring starts at the defined distance within the primary object.

-

Ring Thickness

Defines the thickness of the ring.

ZOI Class

This additional parameter is only available if you have selected the Zone of Influence (ZOI) method.

-

ZOI Width

Allows you to set the distance of border of the ZOI from the border of the ring, or the main object, respectively.

Segmentation Method

Displays and selects a segmentation method for the currently selected class with the dropdown.

-

Explore

Opens the dialog to explore and select an available segmentation method, see Segmentation Method Selection Dialog.

3D Parameters

If you are setting up a 3D analysis, the available parameters are either grouped under 2D Parameters for general (2D optimized) parameters, or under 3D Parameters, if the parameters are specifically optimized for 3D operations.

The visible parameters depend on the selected segmentation method. The following parameters sections can be available:
