This ImageJ plugin creates the component tree of the given image and reconstructs the associated threshold stack by coloring the individual components. The component tree is the basis of the MSER feature detection algorithm. The user may choose from two different component tree algorithms:

  1. "global immersion" (quasi-linear time) or
  2. "local flooding" (linear time).

See Sec. 26.2 of [1] for details. If no image is currently open, the user is asked to load a predefined sample image. Note: This implementation is quite inefficient since the image pixels contained in each tree component must be collected recursively at each threshold level for visualization. Use on small images only!
