摘要:

给出了一种大容量索引图像中水印方案的设计与实现。利用了图像置乱和模式识别技术,在嵌入水印时参考了HVS(human visual system)进行水印嵌入调整。实验表明该方案可以有效地满足实际应用中要求的抵抗剪切、拼接、涂改攻击和不可见性。

关键词: 数字水印, 索引图像, 图像置乱, 模式识别

Abstract:

Based on image scrambling and pattern recognition, a new watermarking scheme in huge index image is proposed. The scaling parameter according to HVS(human visual system) was adjusted by the system while embedding watermarks. The experimental results show that the proposed scheme has a good effect of anti-cutting, anti-modifying, anti-patching and invisibility.

Key words: digital watermark, index image, image scrambling, pattern recognition
