| 摘 要： | 目前许多关于图像融合的研究都在空域中进行,隐藏水印图像抗攻击的能力较差.本文采用了基于小波变换的图像融合技术,提出了基于小波变换的分块融合算法,使图像的鲁棒性得到很大提高,尤其是抗JPEG压缩和抗噪声干扰的能力较强,算法可应用于数字图像的版权保护和信息隐藏领域.

| Abstract: | Much research into image fusion has been carried out in the spatial domain.However,the hidden watermarking image's resistance to attacks is relatively inferior when image fusion is conducted in the spatial domain.We develop a image fusion technique based on wavelet transform.By analyzing the image fusion model in the wavelet domain,we propose the segment fusion algorithm that is based on wavelet transform.The proposed algorithm improves the images' robustness significantly,especially their resistance to JPEG compression and noise disturbances.The algorithm can be applied in various fields such as copyright protection of digital images and information hiding. |
