Revival of a 14 years old code (written in 1991 for MATLAB 2.x). Given a set of measured x,y pairs that a re supposed to reside on a circle, but with some added noise. A circle to these points, i.e. find xc,yc,R, such that (x-xc)^2+(y-yc)^2=R^2 The method minimizes the sum of squared radial deviations.

here to import the pictures and how to segment the picture. how to add the noise. some screen shots will be added this file.
