摘要

水印嵌入位置的选择对水印的鲁棒性和图像的视觉质量具有重要影响.提出一种基于SVR算法的自适应数字化图像水印方法,旨在实现水印嵌入位置的精准选择和水印信息的有效保护.实验结果表明,采用本方法处理后的水印图像PSNR值达到46.4 dB,与原始图像的PSNR值误差仅为3.39 dB,图像质量保持良好.同时,LOD值超过98%,证明该方法能精准识别适合嵌入水印的区域、实现高效、准确的水印嵌入.

Abstract

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.
