| Abstract: | In this paper we address the problem of usingquaternions in unconstrained nonlinear optimiza-tion of 3-D rotations. Quaternions representing ro-tations have four elements but only three degreesof freedom, since they must be of norm one. Thisconstraint has to be taken into account when ap-plying e. g. the Levenberg-Marquardt algorithm |
