In order to further demonstrate the effectiveness of our proposed ST_D features for real steganalytic systems, we performed a similar experiment on compressed video sequences in MPEG2 format by using ST_D, RM, SPEAM and SPAM features.
5 implies that RM, SPAM and SPEAM features exhibited similar performance, whereas the ST_D features had substantially better performance in all of the cases tested, suggesting that this device may generate more information useful for video steganalysis.
The results are similar to those obtained for videos compressed in MPEG2 format, illustrating that the ST_D features are generally advantageous for video steganalysis compared with SPAM and SPEAM features, especially for compressed videos, which constitute most Internet videos.
In this work, several comparative experiments were conducted, and the experimental results confirm that our proposed features are much more effective than RM features with high dimension, SPAM features and SPEAM features, especially for compressed videos that are the major components of the Internet videos and may, thus, be of practical and commercial value.
