The invention relates to a method for watermark embedding in multi views video comprising a plurality of views captured with a plurality of cameras comprising for each view a step of projecting the view (I) onto a domain invariant to the plurality of views and to intermediate synthesized view, which depends on the locations, orientations, and intrinsic parameters of the cameras, resulting into an invariant vector (i) ; a step of applying a watermarking algorithm to the invariant vector (i) resulting into a watermarked invariant vector (i w ) ; and a step of modifying the view (I) to obtain a watermarked view (I w ), wherein said watermarked view (I w ) when projected onto the invariant domain results into the watermarked invariant vector (i w ). The invention also relates to a method for watermark detection in a rendered view comprising a step of projecting the rendered view onto an invariant domain to the plurality of views resulting into an invariant rendered vector; a step of applying a watermark detection algorithm to the invariant rendered vector in order to assess the presence of a watermark. |
