Global Thresholder (deprecated)

A thresholder thresholds the intensity values of an image according to a given threshold. The result is a binary segmentation. Please note that you have to use the Connected Component Analysis Node after the thresholding analysis to extract a segmentation with seperated segments. For details see: "Survey over image thresholding techniques and quantitative performance evaluation" Sezgin04.

Options

Manual Threshold

The threshold value used if MANUAL is used as threshold value.

Thresholding method

The thresholding method to determine the threshold

Dim selection

The dimensions for which the threshold value is calculated (if a automatic method is selected)

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.
