Fast watermarking scheme for real-time spatial scalable video coding
作者：
Highlights：
• HVS watermarking algorithm is proposed for spatial coding using the H.264/SVC.
• Extracts textural feature using quantized coefficients to classify textured blocks.
• Embeds watermark into classified textured blocks, which is repeated for all layers.
• Proposed method exhibits quality degradation of ~0.36 dB at 2.18% bitrate overhead.
• Proposed method is also robust towards post-processing attacks at any coding layer.
