This paper presents a formulation for minimizing the equal error rate (EER) in multimodal biometrics fusion. By utilizing a linear parametric model and a constrained optimization framework, the solution to the EER minimization problem can be translated into a tuning task for the Lagrange multiplier. The formulation is experimented on a fusion task, combining the scores of an infrared face system and that of a visual face system. Our preliminary result shows stability of fusion which is very encouraging.
