スポンサーリンク
概要
- 論文の詳細を見る
A quantization-based watermarking system for motion pictures is proposed.In particular, methods for improving the image quality of watermarked video, the watermarking data tolerance, and the accuracy of watermark data detection are described.A quantitative evaluation of the reliability of watermarked data, which has not generally been discussed up to now, is also performed.
