在这份报纸,以便增加隐藏信息的数量,我们选择 MPEG 序列为搬运人并且在 MPEG 在 steganographic 方法上介绍一个实际方法焦点压缩录像序列。通常,在每 GOP 有许多 B 框架。我们利用 B 框架隐藏信息以便我们能增加隐藏信息和减少的数量搬运人的 tamper。没有要求原来的录像,躲并且提取在压缩录像序列被执行。试验性的结果证明建议方法有没有增加搬运人文件的体积,在视觉效果和更大的躲能力上捣弄的更少的特征。
In this paper,in order to increase the amount of hiding information,we choose MPEG sequences as carriers and present a practical method focus on the steganographic method in MPEG compressed video sequences.Generally,there are many B-frames in each GOP.We utilize the B-frames to hide information so that we can increase the amount of hiding information and decrease the tamper of the carriers.Hiding and extracting are performed in compressed video sequences without requiring original video.The experimental results show that the proposed method has the characteristics of less tampering on the visual effect and larger hiding capacity without increasing the volume of the carrier file.
