Abstract
The temporal correlation between adjacent video frames poses a
severe challenges for video watermarking applications.
Motion-coherent watermarking has been recognized as a strategy to
embed watermark information in video frames, resistant to
collusion attacks. The motion-compensated temporal wavelet
transform (MC-TWT) provides an efficient tool to separate static
and dynamic components of a video scene and enables
motion-coherent watermarking.
In this paper, we extend a MC-TWT domain watermarking scheme with
blind detection, i.e. motion estimation and watermark detection
is performed without reference to the unwatermarked video. Our
results show that motion-coherent watermarking can be combined
with a blind detector, widening the applicability of MC-TWT
domain watermarking beyond forensics (where the unwatermarked
content is assumed to be available).
