Zb. Lei et Db. Cooper, LINEAR-PROGRAMMING FITTING OF IMPLICIT POLYNOMIALS, IEEE transactions on pattern analysis and machine intelligence, 20(2), 1998, pp. 212-217
A new implicit polynomial (IF) fitting method is presented. It provide
s a different way of viewing the IP fitting problem from those of the
nonlinear optimization approaches. It requires less computation, and c
an be done automatically or interactively. Linear Programming (LP) is
used to do the fitting. The approach can incorporate a variety of dist
ance measures and global geometric constraints.
