基于图像特征的彩色图像防拷贝水印算法
Feature-based watermarking algorithm for color image resistant to copy attack
摘要
Abstract
The rapid developments of digital signal processing and internet techniques have threatened the copyright protect of the digital productions severely. Digital watermarking can realize the copyright protection and authentication for the digital data by hiding some digital information in them. In this paper , a novel watermarking algorithm for color image resistant to copy attack is proposed. The method a-dopted YUV color space and the feature describing the original image uniquely is attained by DCT and binarization from the chroma component. After being scrambled by chaotic sequences, the feature is embedded into the middle frequency coefficients of luminance components of the color image by using DWT. The extracting does not need the original image, namely a blind watermarking algorithm. The simulations show that the scheme can effectively resist not only common image processing such as noise,JPEG compression,filtering,cropping,etc,but also copy attack. .关键词
