CONCEAL: A robust dual-color image watermarking scheme
作者：
Highlights：
• A dual-color watermarking based on inter-block matrix decomposition is proposed.
• A novel diagonal relationship is developed to embed the watermark.
• The amount of data for color watermark is reduced by combining compressive sensing.
• Matrix decomposition is used for the first time between surrounding inter-block.
• Results show a large embedding capacity, excellent imperceptibility and robustness.
