thread962-142103: How to find the inital formula from engineering test data
hi  FreddyMusic how did u get the perfect curve..pls help me...

I have extracted blood vessels from fundus image.I have to find the coordinates of the subvessel.I have done using find function but not correct for all subvessels.So I have to trace the coordinates from start end point to last end point.I am thinking to try using 8 connected component concept.Is there any other method possible..give your idea...
I have to get function y=f(x) for the curve.I have tried using curve fitting but not getting exactly..Help me if u have any idea in this....
