Morphological Labeling Operations

Perform morphological operations on labelings.

Options

Connection Type

• Four-Connected
• Eight-Connected
• Structuring Element: Read the structuring element from the optional second in port.

Structuring Element

Column of the structuring element.

Operation

• Erode: Erode labeled areas.
• Dilate: Dilate labeled areas.
• Open: Erode followed by Dilate. Erases tiny labeled spots.
• Close: Dilate followed by Erode. Erases small holes in labeled components.

Strategy

• Individual Labeling: Erode/Dilate each label individually. This means, labels may also overlap.
• Binary: Erode/Dilate each pixel with none/any labeling in the neighborhood. In short: we don't distinguish between the individual labels and treat any labeled pixel as positive.

Dimension Selection

Determines for which dimensions the morphological operations will be applied individually.

Out of Bounds Strategy

The 'OutOfBounds Strategy' is used when an algorithm needs access to pixels which lie outside of an image (for example convolutions). The strategy determines how an image is extended, for examples see Fiji Wiki

Column Selection

Column Creation Mode

Mode how to handle the selected column. The processed column can be added to a new table, appended to the end of the table, or the old column can be replaced by the new result

Column Suffix

A suffix appended to the column name. If "Append" is not selected, it can be left empty.

Column Selection

Selection of the columns to be processed.

Views

Image Viewer

Another, possibly interactive, view on table cells. Displays the selected cells with their associated viewer if it exists. Available views are:
- Image Viewer
-- This viewer renders the selected image-cell.
- XML
-- XML tree
- Combined View
-- A viewer shown when the user selects an interval of rows and columns in the viewer. This viewer combines all images and labelings in the selected interval to one image by rendering them next to each other. Alternatively, the images and labelings can be layed over each other.
- BigDataViewer
-- A viewer shown when the user selects an interval of rows and columns in the viewer. This viewer combines all images and labelings in the selected interval to one image by rendering them next to each other. Alternatively, the images and labelings can be layed over each other.
- Labeling View
-- View on a labeling/segmentation
- Histogram Viewer
-- This viewer shows the histogram of the currently selected image.
- Missing Value Viewer
-- An empty viewer that is shown when the input cell has no value to display.
