摘要
文章提出了一种基于HVS模型的JPEG2000数字图像水印算法,该算法根据计算原始图像嵌入水印的能力限制和数据量化方法进行水印的嵌入与提取。实验证明,该算法对于常用的图像处理方法以及JPEG2000编码在保持了较好质量的基础上有较强的鲁棒性。
This paper introduces a watermark algorithm based on the HVS model of JPEG2000 digital image.The algorithm adopts the limitation for the computation result of the capability of embedded original image and the method of data quantization to embed and extract.Experimental results show that the proposed algorithm keeps the quality of the image well and is robust against common image processing operations and JPEG2000 Coding.
