【摘要】 介绍一种采用三级小波分解的数字水印技术,利用多分辨率技术,分别将原始图像和水印图像进行三层离散小波变换,将同频带的不同层次的水印嵌入到同频带的图像当中,并取得了良好的试验结果。试验证明,该算法经过某些图像处理操作以后仍然是鲁棒的。更多还原

【Abstract】 This paper introduces a kind of digital watermarking technology with the use of three-level wavelet decomposition.Firstly,the watermarking image and raw image in multi-resolution is decomposed using DWT,and then different level watermarking is added into the raw images with the same scale.Experimental results show that this algorithm is robust against some image processing.更多还原
