Frame Untangling for Unobtrusive Display-Camera Visible Light Communication

Pairing displays and cameras can open up convenient and "free" visible light communication channels. But in realistic settings, the synchronization between displays (transmitters) and cameras (receivers) can be far more involved than assumed in the literature. This study aims to analyze and model the temporal behaviors of displays and cameras to make the visible light communication channel between the two more robust, while maintaining perceptual transparency of the transmitted data.
