Labkit is a FIJI plugin for:

  • automatic image segmentation
  • labeling regions of an image

The automatic image segmentation functionality is comparable to Trainable Weka Segmenation, but it's better suited for large 3d images. And it has a nice Big Data Viewer based editor.


Labkit can be installed from the ImageJ update site: (For details on how to install an update site click here.)


Use ImageJ to open the image you want to create labels for. In ImageJ, select the image, and from the menu choose Plugins > Segmentation > Labkit.


Basic Navigation

  • ^ Ctrl+ Shift+mouse-wheel to zoom in and out
  • right-click+drag to move the image
  • left-click+drag to rotate a 3d image
  • mouse-wheel to scroll through the z-slices of a 3d image

Create Labels

When Space is pressed, while the mouse is over the image, a circle around the mouse pointer will appear.

  • Space+left click mark the pixels inside the circle
  • Space+right click remove the mark from the pixels inside the circle.
  • Space+mouse wheel change the size of the circle used to mark pixels.

By default pixels can be marked as "foreground" or "background". To switch between these two labels use N.
