Uh yeah. Why not just do
topLine = [50,30; 50, 190]; % The x,y coordinates where each row is one endpoint.
bottomLIne = [100,30; 100, 190];
leftLine = [50,30; 100,30];
rightLine = [50,190; 100,190];
If you don't mean that , then you'd better explain specifically what you mean by "4 groups".

Michael's "Answer" moved here since it's not an Answer to the original problem.
Not that, I mean here is the image:

I can think of a few methods. What are you thinking of? You could use RANSAC or use traditional image processing methods (like convhull, activecontour, morphological closing, etc.) and try to extract out upper, lower, left, and right parts and then call polyfit().
