摘 要: | 提出了一种基于人类视觉系统特性的和DCT变换的图像水印算法,首先根据HVS特征计算载体图像每个分块的嵌入阈值,然后利用阈值实现水印在不同分块的自适应嵌入。通过仿真实验,算法在确保鲁棒性的基础上实现了较好的透明性。

Adaptive Digital Watermarking Based on HVS |
| |
Abstract: | An Image Watermarking algorithm based on DCT is proposed using the characteristics of the human visual system. First of all, calculating the embedding threshold according to HVS features, and then using the threshold for adaptive embedding watermark in different block. The algorithm ensuring the robustness and achieve the better transparency through simulation experiments. |
