- Hi all,
- I was just wondering if anyone has or
- knows of general purpose contour tracing and
- contour filling software in C or Lisp
- (such as efficient implementations of
- the algorithms in Pavlidis).
-
- I'm interested in the following 2 problems:
- a) Given a 2D array with several binary shapes
- I'd like to be able obtain a separate list of contour
- points for each contour that is ordered
- according to a CW or CCW trace of that contour.
-
- b) Given an array with several contours I'd like to
- be able to selectively fill each contour with a
- binary value.
-
- Please send replies to kal@lems.brown.edu
- thanks!
- -Kaleem
