WATERMARK DETECTION USING A PROPAGATION MAP |
摘要 |
A method for detecting and selecting watermarking in video coding is provided that comprises accessing a list of possible watermarks; generating propagation maps of modifications to the video that would be caused by applying the respective watermarks; generating a detection region responsive to each respective propagation map that includes blocks within the propagation map that collectively rank highest with respect to a selected detection criteria compared to each other region within the propagation map; selecting a threshold metric for evaluating detection regions; and removing watermarks from the list responsive to a comparison of their detection regions with the threshold metric. |
