This is a fast implementation of the GrowCut method. The algorithm uses example segmentation to create a full segmentation of the volume. It supports multi-label segmentation and user online interactions. Please see the references below for more details.

<!--Here comes a description what the module is good for. Explain briefly how it works and point to the [[documentation/{{documentation/version}}/Modules/{{documentation/modulename}}#References|references]] giving more details on the algorithm.

−

Step 1.) Add data volume to segment

−

Step 2.) Go to the “Editor” module, select the volume loaded in Step 1 as the “Master Volume” in the “Create and Select Label Maps” drop-down menu

−

−

Step 3.) Select the “FastGrowCutEffect” effect in the “Edit Selected Label Map” drop-down menu

−

−

Step 4.) Press the “Start Fast GrowCut” button ( FastGrowCut is now running in the background until the “Stop FastGrowCut” button is pressed)

−

Step 5.) Turn “On” all three slice views in the 3D Plane

−

−

Step 6.) Initialize the segmentation using fast GrowCut

−

* (a) go to PaintEffect to draw seed regions (label 1 for foreground and 2 for background), then press 'G' to run fast GrowCut.

−

−

* (b) If not satified, press 'S' to toggle between seed image and segmentation result. Edit on the seed image to reduce over/under segmentaions. 

−

−

* (c) Once finished editing on the seed image, press 'G' to run fast GrowCut again.

The steps 6 (b) and (c) may be repeated a couple of times until satisfied.
