Multi-symbol QIM video watermarking

作者：

Highlights：

• Theoretical framework for the binary m-QIM (multi-symbol quantization index modulation).

• Detection method optimized with respect to the minimization of the average error probability.

• Expected benefit: for prescribed transparency and robustness constraints, the data payload is increased by a factor of log2m.

• Experimental validation: robust and semi-fragile MPEG-4 AVC watermarking.
