基于FRFT及HVS的自适应数字水印算法
Adaptive digital watermarking algorithm based on FRFT and HVS
摘要
Abstract
In order to improve the robustness and security of digital watermarking,this paper proposed an adaptive color digital watermarking algorithm based on FRFT and HVS by analyzing the human visual masking properties.It used spectral measurement to structure texture masking factor of the host image,and combed it with the luminance and the edge masking factors to structure adaptive masking factor of the color host image,regarded the adaptive masking value as the embedding strength.It the color watermark was embedded by modifying the FRFT intermediate frequency coefficients of the color host image.The experimental results show that the algorithm has good adaptive ability,invisibility,security and so on.关键词
