Abstract

Abstract: A spatial domain image watermarking algorithm based on chaotic maps is proposed.Fist，the visual factor of each pixel is computed by the use of luminance，edge，texture characteristics of the host image，and then the embedding bit can be determined by the visual factor and chaotic maps，and finally the watermark bit is embedded into the image by simple bit substitution.The watermark extraction needn’t resort to the original image.Simulation results demonstrate that the embedded watermark is invisible and the watermarking scheme is robust to common signal processing operations.

摘要： 提出一种基于混沌序列的图像空域水印算法。首先通过亮度、边缘、纹理特性计算出每象素视觉因子；然后由视觉因子和混沌映射确定每象素水印嵌入比特位；最后通过替换方式嵌入水印。水印提取时不需原始图像的参与，实验表明算法具有较好的水印透明性，并对一般信号处理攻击是鲁棒的。
