Based on the research paper "A Simple approach for the Estimation of Circular Arc Center and Its radius", Thomas and Chan, Computer vision, graphics and image processing 45, 362-370 (1989)
All credits go to above authors and Landau who originally proposed this method. Use of geometric fit makes this more accurate than least square approximations.
How to use?
[xc,yc,R] = Landau_new(x,y);
%where x and y are column vectors with data to be fitted.
%xc and yc are the center of fitted circle with radius R. |
