一种自适应的奇偶量化水印算法
Adaptive odd-even quantization watermarking algorithm
摘要
Abstract
Watermarking is an effective method of multi-media copyright protection.This paper proposes a novel odd-even quantization watermarking algorithm, the quantization step is adaptively determined and controlled by Watson model and JPEG quantization table.The watermark is embedded in the mid-frequency coefficients of DCT.Because of odd-even quantization, watermark can be exacted very easily.Experimental results show the algorithm has good invisibility, and is robust to some common image processing and noise attacks.关键词
