A robust watermarldug scheme using filter and ROI
Der‐Chyuan Lou, Jiang-Lung Liu, Hao-Kuan Tso · 2005
In this paper, a robust watermarking technique for copyright protection is proposed. The proposed scheme is different from most existing schemes. By using the concept of filter technique to embed the watermark into the R01 (region-of-interest) images, the proposed scheme overcomes the problem that watermark embedded into the spatial domain can be destroyed easily after image processing attacks. The experimental results show that besides the invisibility and security, the scheme is also robust against signal processing attacks.
