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".

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().
