Zikai Xu, Bin Liu, Weihai Li, Lijunxian Zhang, Nenghai Yu

TL;DR
SiGRRW introduces a novel single-watermark reversible watermarking framework that enhances robustness and imperceptibility while ensuring lossless recovery, applicable to both generative models and natural images.
Contribution
It proposes a guiding strategy for a single-watermark RRW framework, overcoming limitations of two-stage schemes and improving capacity, robustness, and imperceptibility.
Findings
Outperforms existing RRW schemes in robustness and imperceptibility.
Maintains lossless recovery of cover images.
Achieves higher capacity than conventional schemes.
Abstract
Robust reversible watermarking (RRW) enables copyright protection for images while overcoming the limitation of distortion introduced by watermark itself. Current RRW schemes typically employ a two-stage framework, which fails to achieve simultaneous robustness and reversibility within a single watermarking, and functional interference between the two watermarks results in performance degradation in multiple terms such as capacity and imperceptibility. We propose SiGRRW, a single-watermark RRW framework, which is applicable to both generative models and natural images. We introduce a novel guiding strategy to generate guiding images, serving as the guidance for embedding and recovery. The watermark is reversibly embedded with the guiding residual, which can be calculated from both cover images and watermark images. The proposed framework can be deployed either as a plug-and-play…
