Face recognition in controlled environments is nowadays considered rather reliable and, if face is acquired in proper conditions, a good accuracy level can be achieved by state-of-the-art systems. However we show that, even under these desirable conditions, some intentional or unintentional face image alterations can significantly affect the recognition performance. In particular, in scenarios where the user template is created from printed photos rather than from images acquired live during enrollment (e.g., identity documents), digital image alterations can severely affect the recognition results. In this chapter, we analyze both the effects of such alterations on face recognition algorithms and the human capabilities to deal with altered images.

Abstract

Face recognition in controlled environments is nowadays considered rather reliable and, if face is acquired in proper conditions, a good accuracy level can be achieved by state-of-the-art systems. However we show that, even under these desirable conditions, some intentional or unintentional face image alterations can significantly affect the recognition performance. In particular, in scenarios where the user template is created from printed photos rather than from images acquired live during enrollment (e.g., identity documents), digital image alterations can severely affect the recognition results. In this chapter, we analyze both the effects of such alterations on face recognition algorithms and the human capabilities to deal with altered images.
