摘要:
A method and system for embedding data in video frames is described, the method comprising receiving marking information, representing the marking information as a 2-coordinate vector, denoted ϖ, where the 2-coordinates are denoted, respectively, α, β, such that ϖ = (α, β), providing a video frame to be marked, the video frame including a plurality of pixels, each pixel of the plurality of pixels being represented as p, where p = (x, y), x and y including coordinates of pixel p, the plurality of pixels being represented as a triad of color elements, denoted, respectively, as R, G, and B, and marking the video frame by transforming each pixel among the plurality of pixels as follows R'(p) = R(p) + , G'(p) = G(p) + , and B'(p) = B(p) + , where represents a dot product operation on p and ϖR, represents a dot product operation on p and ϖG, and represents a dot product operation on p and ϖB.
