摘　　要：利用改进广义的Henon映射,结合人眼视觉模型,在数字图像的小波树结构域下,进行数字水印的嵌入和提取。试验表明,这种水印嵌入算法,能在保证不可见性的基础上,较好地对数字图像进行加密,对噪声攻击、压缩攻击和剪切攻击都有很好的抵抗性。Using the improved generalized Henon maps,we propose a blind watermarking method based on wavelet tree and human visual system （HVS）. We simulate the algorithm in the computer and test the performance of watermark embedding, watermark extraction and the detection, extraction and recovery of the embedded watermark after different kinds of attacks. Experimental results show that the algorithm is feasible and robust.
