                 Mean Shift Analysis Library
    =============================================
 
    The mean shift library is a collection of routines
    that use the mean shift algorithm. Using this algorithm,
    the necessary output will be generated needed
    to analyze a given input set of data.
 
  Region Adjacency List:
  =====================
 
    The Region Adjacency List class is used by the Image 
    Processor class in the construction of a Region Adjacency
    Matrix, used by this class to applying transitive closure
    and to prune spurious regions during image segmentation.
 
    The prototype for the RAList class is provided below. Its
    defition is provided in "RAList.cc".
 
The theory is described in the papers:
 
  D. Comaniciu, P. Meer: Mean Shift: A robust approach toward feature
                                     space analysis.
 
  C. Christoudias, B. Georgescu, P. Meer: Synergism in low level vision.

Implemented by Chris M. Christoudias, Bogdan Georgescu
