I'm working with what is a well-defined problem in image processing,
and need to find some source code for the analysis.

I have a grI am defining were each point on the grid has a 
color or NULL associated with it, ie:
	25	25	27	28	01	-1	-1
	25	-1	28	28	-1	-1	-1
	25	-1	28	28	-1	-1	-1
	-1's down to form 7x7 grid <in this instance>.

I need to be able to analyze this and see a curve that is
not closed-form of 25's, a point which is 27, a closed-form
curve which is 28's, a point which is 01's, and ignore the -1's.


Is there a general algorithm ideally, source code> which
ireadily avlable?

Thanks for any help or guidance,
