We propose a new paradigm for blind watermark decoding in the presence of desynchronization attacks. Employing Forney-style factor graphs to model the watermarking system, we cast the blind watermark decoding problem as a probabilistic inference problem on a graph, and solve it via message-passing. We study a wide range of moderate to strong attacks… CONTINUE READING
