Abstract:
Synchronization problems are still challenging issues in image watermarking field. In this paper, we present a robust image watermarking for projective deformations produced by print-cam system. The approach associates watermark insertion in invariant domain based on Fourier transform with correction pre-process for projective distortions, blur and color degradations. The robustness of the proposed method is tested and compared with different existing approaches. The comparison test is presented with simulated projective distortions and with real print-cam system using two different smartphones (iPhone6 and Samsung S5). The results show better performance of the proposed method in term of robustness, compared with other tested methods.
