【Abstract】 A lot of researches on image fusion have been carried out in the spatial domain.However,the hidden image’s resistance to attacks is relatively inferior when image fusion is conducted in the spatial domain.In this paper,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.更多还原
