We present a new method, called "EFNS" ("extended FNS"), for linearizable constrained maximum likelihood estimation. This complements the CFNS of Chojnacki et al. and is a true extension of the FNS of Chojnacki et al. to an arbitrary number of intrinsic constraints. Computing the fundamental matrix as an illustration, we demonstrate that CFNS does not necessarily converge to a correct solution, while EFNS converges to an optimal value which nearly satisfies the theoretical accuracy bound (KCR lower bound).
