Uber-in-Light

https://github.com/mostafaizz/uber-in-light
Designed and developed a communication application that embeds hidden messages inside the pixels of a transmitted video stream via a screen. The receiver in this communication would be any digital RGB camera, where we can synchronize the camera and the screen and extract the hidden messages in near-real-time processing. We also published the results of this project for the top-tier conference, INFOCOM.
