摘要

提出了一种基于人类视觉系统模型的半调技术——直接二分搜索(DBS)的扩频图像水印算法。利用DBS设计了一种基于误差度量和相关水印检测器输出的共同优化人眼视觉系统的半色调。相关水印检测需要原始图像。

Joint halftoning and watermarking

A spread spectrum watermarking algorithm for hardcopy imaging applications using a human visual system model based halftoning technique called direct binary search (DBS) is presented. DBS is used to design a halftone that jointly optimizes a human visual system based error metric and correlation watermark detector output. The original image is required for the correlation watermark detector.
