Message Adaptive Embedding Algorithm for Visible Light Implicit Imaging Communication Based on Dynamic Video

针对可见光隐式成像通信系统中动态视频作为发送端信息载体时视频帧间存在差异的问题,分析动态视频帧图像实时变化的特点和帧间差异对信息传输造成干扰的原因,提出一种互补帧调制的自适应信息嵌入算法。该算法以动态视频作为隐式信息传输的载体,实现系统的可靠传输并有效地避免静态图像作为载体时的单一性。测试实验结果表明,该算法解决了动态视频帧间差异导致的系统误码性能降低的问题,并且改善隐式信息的视觉无感效果。

In order to address the difference between video frames in the visible light implicit imaging communication system when dynamic video is used as the transmitter information carrier, this paper proposes amessage adaptive embedding algorithm based on complementary frame modulation. In this paper, the characteristic of real-time changes of dynamic video frames and the reasons for the interference of information transmission caused by the difference between frames are analyzed.The algorithm uses dynamic video as the transmitter carrier of implicit information, which realizes the reliable transmission of the system and effectively avoids the singularity of the static image as a carrier. The experimental results show that the proposed algorithm solves the problem of reduction for system error performance caused by the difference between dynamic video frames, and improves the visual non-inductive effect of implicit information.
