Digital Watermarking Algorithm Based on SVR
Xiuli Bi · Modern Electronics Technique · 2011
A new digital color image watermarking algorithm based on support vector regression(SVR) is proposed.The feature vector can be selected in the wavelet domain and the train model can be obtained by applying the support vector regression theory.The watermark signal can be embedded or extracted by utilizing the above train model.The proposed scheme can extract the digital watermark without the help of the original digital image.Experimental results show that the proposed scheme is invisible and robust against common signal processing such as noise adding,JPEG compression,sharpening,smoothing,filtering,contrast enhancement,shearing and so on.Especially,it performs better than other image watermarking schemes based on support vector machine.
