A Video Watermarking Scheme for Broadcast Monitoring
Jing Li · Computer Knowledge and Technology · 2013
According to the problem of video authentication in broadcast monitoring,A watermark scheme based on video features was proposed.Firstly,the video features were extracted by using 3D discrete wavelet transform and discrete cosine transform,then the video features and watermark identifier information created watermark.Secondly,the human visual characteristics were used to select a self-adaptive embedding locations,after that,the spread spectrum communication technology solution was applied to in crease the watermark robustness.Academic analysis and experimental results show the scheme can resist various attacks and has good real-time capabilities,the scheme can be used to video authentication.
