Method of watermarking a color image by vectorial approach, method of detecting a mark of watermarking, corresponding devices, image and computer programs

摘要

A method of watermarking a color image that has at least three components is provided. Such a method of watermarking includes an insertion step of a mark of watermarking, on at least one point of the image, according to an insertion rule taking into account the relative position of at least three component vectors, associated to said at least one point.
