| Summary: | To authenticate the integrity of stereo image,an asymmetrical stereo image watermarking scheme based on binocular suppression was proposed.Firstly,according to the features of stereo vision,the computation of binocular sup-pression model was established.The concept of asymmetric stereo image watermarking was defined that two views of stereo image were embedded with different data payloads.Then,discrete wavelet transform was employed to generate different types of recovery watermark for each block,and their copies were embedded into two or three different mapping blocks to improve the quality of recovery.The experimental results demonstrate that the proposed method can detect and recover different kinds of tamper effectively,such as collage attack,and the recovered quality is better than those of other existing and extended mono-image watermarking methods. |
