Description:
The Watershed module is a segmentation tool for 3D data using a step function (Volkmann, N. (2002). A novel
three-dimensional variant of the watershed transform for segmentation of electron density maps.
J. Struct. Biol. 138: 123-129).
It connects regions which have the similar values in one region and labels them with a unique number. From the threshold
new labels will be generated and existing labels will be expanded. Pixels which have a higher value than
Maximum_threshold_for_new_labels are labeled with 0. With the number of steps you can control the increasing value
between threshold and Maximum_threshold_for_new_labels.
The segmentation process is started, when the Apply button is pressed.
Ports:
Threshold
From the number enterd here the labeling will be started. Regions below this threshold will have a unique number.
Steps
How many steps should be performed? The steps are used to overcome some noise and avoid creating a label for
each noise spot.
Maximum threshold for new labels
Up to this number the image will be labeled. Every values above this number will be set to zero.
