Optimal Sub-bands Decision for Robust Watermarking
Yoon-ho Kim, Myung-kil Lee, Yoon-shick Kwak · Proceedings of KIIT Summer Conference · 2006
This paper is concerned with a method of optimal sub-bands decision based on fuzzy inference. It concentrated on the design of fuzzy inference algorithm as well as discrete cosine transform(DCT) and human visual system. Firstly, feature parameters are extracted by using characteristics of the coefficients matrix of DCT. Secondly, fuzzy if - then rule which can be able to adapt the wide variety of environments is developed. The performance of proposed scheme is evaluated with respect to the imperceptibility and correctness of watermark.
