Adaptive digital image watermarking method based on SVR algorithm
The selection of watermark embedding location has great influence on the robustness of watermark and the visual quality of image.In this paper,an adaptive digital image watermarking method based on SVR algorithm is proposed to realize the precise selection of watermark embedding position and the effective protection of watermark information.The experimental results show that the PSNR value of the watermark image processed by this method reaches 46.4 dB,and the error is only 3.39 dB com-pared with the original image.At the same time,the LOD value is more than 98%,which proves that this method can accurately identify the region suitable for embedding watermark and realize efficient and accurate watermark embedding.
