【摘要】 数字视频内容的认证技术越来越成为研究的热点。基于云水印及镜头分割技术,提出了一种新颖的视频内容认证方案。论文就不变特征提取、云水印生成、嵌入和提取、视频的认证与篡改检测等技术进行了研究并进行了实现。通过实验分析和验证,该方案可对实时的视频进行认证而不影响视频本身的视觉效果。更多还原

【Abstract】 Digital video content authentication technique becomes a hot point.A novel video content authentication scheme,based on cloud watermark and shot segmentation,is proposed.The related technique on the Invariant Feature extraction,the generation of the cloud watermark,the embedding and the extraction of cloud watermark,the authentication and the tamper detection on video were studied and implemented.With some experiments and the corresponding analysis and the verifying for the results,the scheme can be applied into the real time video and may not affected the visual efficient.更多还原
