      The image foresting transform (IFT) is a graph-based approach to
      the design of image processing operators based on
      connectivity. It naturally leads to correct and efficient
      implementations, and to a better understanding of how different
      operators relate to each other. We give here a precise
      definition of the IFT, and a procedure to compute it---a
      generalization of Dijkstra's algorithm---with a proof of
      correctness. We also discuss implementation issues and
      illustrate the use of the IFT in a few applications.
