Local Geometric Distortions Resilient Watermarking Scheme Based on Symmetry
IEEE Transactions on Circuits and Systems for Video Technology(2021)
摘要
As an efficient watermark attack method, geometric distortions destroy the synchronization between the watermark encoder and decoder. Local geometric distortion is a considerable challenge in the watermarking field. Although many geometric distortion resilient watermarking schemes have been proposed, few perform well against local geometric distortions, such as random bending attacks (RBAs). To ad...
