| 摘 要： | 在研究小波变换的基础上,给出了一种基于小波的快速图像隐藏算法.利用小波变换(DWT) 的基本原理,对公开图像进行小波变换,将把小波变换后的系数与秘密图像进行融合,最后利用小波逆变换进行图像重构得到结果图像.数值试验表明该方法的抗攻击能力较强,并保证了很好的视觉质量,且算法简单易行.

| Abstract: | An image hiding algorithm based on wavelet transformation is proposed.Firstly,the secret image is scrambled;Secondly,the opened image is decomposed into low-frequency and high-frequency images,then the wavelet coefficients are calculated.The fused wavelet coefficients are composed, and the fusion image is got by inverse wavelet transform.Finally,the performance of the fusion algorithm is evaluated and analyzed.Experimental results show that the proposed method can embed a large amount of secret Information ... |
