Accurate face registration is of vital importance to the performance of a face recognition algorithm. We propose a new method: matching score based face registration, which searches for optimal alignment by maximizing the matching score output of a classifier as a function of the different registration parameters (translation, rotation, scale). We compare this method with our previously developed methods, namely MLLL based on maximizing the likelihood ratio in combination with BILBO which corrects outliers in the found landmarks and a Viola-Jones based landmark detector. We determine the accuracy of the registration methods and give an indication of the speed of the methods. Futhermore, we investigate the influence of the registration on the task of face verification.
