Abstract
This paper proposes a novel digital image robust watermarking scheme based on fuzzy theory in wavelet domain.This algorithm makes use of DWT nature that every wavelet coefficient corresponds to an image block,using fuzzy entropy to measure the richness of image texture and brightness of the noise factor to determine the strength of embedded watermarking.Different wa-termarking strength embedded in different image blocks determined by fuzzy entropy and brightness factor can adapt in the image and improve the robustness of the watermarking.The experimental results show that the algorithm can maintain good watermarking transparency,at the same time,further enhance the robustness of the watermarking.关键词
