Module Description
This is a fast implementation of the GrowCut method. It supports multi-label segmentation and user online interactions. Please see the references below for more details.
Tutorials
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 “CarreraSlice” effect in the “Edit Selected Label Map” drop-down menu
Step 4.) Set the “Radius” parameter, the "Number of Iterations" and press the “Start Interactive Segmentor” button ( CarreraSlice is now running in the background until the “Stop Interactive Segmentor” 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.
Step 7.) Once satisfied with the initialization, press 'M' to start KSlice interactive segmentation. The energy functionals available are:
- (a) press 'F' for local-global Chan-Vese segmentation
- (b) press 'U' for mean curvature smoothing
- (c) press 'E' for Chan-Vese segmentation
