Abstract:In this paper, an affine invariant watermarking scheme, robust to geometric attacks, is proposed and applied to face regions. Initially, face regions are unsupervisedly extracted from an initial image and a normalization procedure, invariant to geometric attacks is applied on each of these regions using a set of specific moment criteria. A spread spectrum-based DS-CDMA watermarking scheme is then used in order to provide a multi bits watermark. The multi bits watermark embedding and detection procedures are th… Show more
