A thorough organized treatise of similarity measures for face recognition was presented. All these measures were applied to different typologies of recognition algorithms, so a direct and synoptic comparison of their performances is not possible. Nevertheless, many authors used many of these measures for their algorithms and compared the results, depending on the distances. These kinds of works are precious for making an evaluation and efficiency comparison of these measures, in order to give an overview on the way that can be used and employed for face recognition. This is the aim of the chapter. An analysis of requirements of face recognition algorithms is also provided for the applications of authentication and identification of suspects.
