Active Contour Software

Product Information
  This program allows the user to experiment with a Gradient Vector Flow
  active contour algorithm, as described by Chenyang Xu and Jerry L. Prince
  in "Snakes, Shapes, and Gradient Vector Flow" in the March 1998 IEEE
  Transactions on Image Processing, Vol. 7, No.3. Additional information,
  including references to research papers, is available via Cheyang Xu's
  web page: http://iacl.ece.jhu.edu/projects/gvf/.

  Active contours are also described as "snakes", because they writhe and move
  under the influence of external and internal forces, toward a feature of interest
  in an image, usually an edge. This program gives the user the opportunity
  to control both external and internal forces to find an optimal set of active contour
  parameters. Active contours are most often used with images to find and describe
  regions of interest.
 
  The Coyote Library (http://www.idlcoyote.com/documents/programs.php) is required
  to run this program.

The program has been completely updated and refurbished to work with other Coyote Graphics
routines as of November 2011. New program documentation  is available from here:
