✖
GrowCutComponents[image,{marker1,marker2,…}]

creates a segmentation from image by growing each markeri.

✖
GrowCutComponents[video,…]

returns segmentation for each frame in video.

Details and Options

  • GrowCutComponents models the image using cellular automata where the automata evolution leads to an image segmentation.
  • GrowCutComponents works with arbitrary 2D and 3D images.
  • Each marker markeri can be given either as an image or a list of points in the standard image coordinate system.
  • The following options can be specified:
  • CornerNeighbors Truewhether to include corner neighbors
    MaxIterations Automaticmaximum number of iterations to use
  • With MaxIterations->Automatic the algorithm runs until convergence.
