中文摘要：
从提高图像变换域信息隐藏算法的隐藏容量角度出发,将迭代混合的思想扩展应用到整数小波变换域,实现了一种新的自适应迭代混合图像隐藏算法。该算法采用整数小波变换,克服了传统小波变换域图像隐藏算法存在的边界误差和舍入误差问题,同时充分考虑人眼视觉特性,有效协调了不可见性和鲁棒性之间的矛盾。实验结果表明算法隐藏容量大,同时具有好的不可见性和鲁棒性。
英文摘要：
In order to increase the capacity of image transform domain information hiding algorithm,this paper applied the idea of iterative blending to integer wavelet domain and presented a novel self-adaptive image information hiding algorithm.The employment of integer wavelet overcame the boundary difference and rounding difference that existed in traditional image information hiding algorithms.Simultaneously,the HVS model was sufficiently used to adjust the imperceptibility and robustness.Experimental results show that the proposed algorithm has a large capacity,good imperceptibility and strong robustness.
