An Adaptive Video Watermarking Scheme Based on the Middle-Frequency Energy Relationship Between Adjacent Frames
基于帧间中频能量关系的自适应视频水印算法

The approximate invariance of the middle frequencies energy relationship between video adjacent frames under photometric distortion and spatial desynchronization is discovered by analysis.Based on this approximate invariance,a new robust video watermarking scheme is proposed.It can adjust embedding strength adaptively according to human visual system features.Experimental results show that the proposed scheme is resilient to photometric distortion,spatial desynchronization and combined distortion effectively.
