摘　　要：旨在分析线性空间隐藏模型下图像无损水印的仿真实验,提出线性空间隐藏模型下无损水印算法提出。通过将原始图像载体划分为图像块序列,结合整数小波变换,获取待嵌水印子带。在0/1水印序列下,结合线性空间隐藏模型,在图像小波域中嵌入水印,不仅提高了水印的鲁棒性,同时也提高了水印的不可见性。结合简单逆向平移的过程,对原始图像进行恢复。对于线性空间隐藏模型,不仅实验了水印的独立性,同时基于无损水印领域,也提高了水印的鲁棒性,并降低误检率,实现原始图像的无损恢复。线性空间隐藏模型下图像无损水印的仿真实验结果表明,算法的应用不仅可以避免有损压缩,同时也有较好的不可见性和安全性。The simulation experiment of the image lossless watermark in linear space hidden model is analyzed and the lossless watermark algorithm in the model is proposed in this paper. The original image carrier is divided into a sequence of image blocks,and the embedding watermark sub-band is acquired in combination with integer wavelet transform. In the watermark sequence of 0/1,the watermark is embedded in the wavelet domain of the image based on the linear space hidden model,which can improve the robustness and invisibility of the watermark. The watermark is extracted by judging the odevity only,and the original image is recovered in terms of the simple reverse translation process. It is pointed out that the linear space hidden model can realize the watermark independence,improve the watermark robustness in the field of lossless watermark,and reduce the false alarming rate. The lossless recovery of the original image was realized. The simulation experiment results of the image lossless watermark in linear space hiding model show that the algorithm can avoid the lossless compression,and has good invisibility and security.
