Watermark techniques based on extension evaluation and SVR in multi-wavelet domain

摘要：

　　A new watermark technique based on extension evaluation and Support Vector Regression (SVR) is proposed in this paper.Extension evaluation is used to calcu late the suitable strength and find the suitable place for the original image after the multi wavelet transform, where watermark is embedded.At the same time, SVR is used to train the study of the relationship between sub-blocks after multi-wavelet transform.Besides, the proposed scheme can extract the digital watermark without the help of the original digital image.Different experiments are conducted to show the performance of the scheme under different types of network attacks.The results show that the proposed scheme can provide a very good imperceptibility and achieve high robustness.
