Image Watermarking Scheme Based on Generalized Arnold Transform and Support Vector Machine
Yong-Gang Fu · Journal of Jimei University · 2011
An image watermarking scheme based on generalized Arnold transform and support vector machine was proposed in this paper.Firstly,the watermark embedding positions and support vector machine training data selection were generated according to the given generalized Arnold transform,then the support vector machine was trained and the randomly permuted binary watermark was embedded into the host.The embedding strength was enhanced based on the watermark strengthen technique.Following the reverse step of the watermark embedding,the watermark could be extracted by the aids of the trained support vector machine.The experimental results showed that the proposed scheme had good robustness against several attacks,such as Jpeg compression,noisy and shearing.
