| 摘 要： | 描述了一种基于MPEG-2视频流的彩色图像信息隐藏方法,该方法利用人眼的视觉特性,可将彩色图像数据隐藏在人眼不敏感的高空间频域及视频运动区域,有较好的隐蔽性,同时采用了视频码率调节的方法,使藏图视频码流长度保持基本不变。该方法在PC机上实验,得到较好的实验结果。

| Abstract: | In this paper,we present a method for hiding a color image in a MPEG-2video based on properties of human visual perception.The color image data is embedded in high frequency parts and moving fast areas that are insensitive to visual perception,which makes better obscurity.We also present a bit rate control method to keep the data size of embedded video varying in a small limited range.With the proposed method,we gain satisfying experimental results on PC. |
