文摘

A novel self-embedding watermarking scheme for tampering recovery is proposed. MSB-layer bits are interleaved with distinct extension ratios to form reference bits. Higher MSB layers have greater probabilities to be recovered than lower MSB layers. Our scheme has better recovered results due to hierarchical recovery mechanism.
