Can anyone please help me with the algorithm for Least-median-of-squares fitting...I am trying to use it for the optic disc segmentation in retinal images?

I never heard of it, though that's not surprising since there are hundreds of papers published every year, each with a unique newly invented filter. You must have heard of it somehow, such as a scientific article or web page. Where was it, and was it not explained in sufficient detail for you to translate the algorithm into MATLAB code?

Actually it just appeared in the Literature review of the paper "Locating the Optic Nerve in a Retinal Image using the Fuzzy Convergence of the Blood Vessels" by Hoover and Goldbaum.So I just wanted to ask what it actually meant and how it was used in the context of Retinal Image processing.
