Abstract
Techniques are generally described for enhanced compression of video data. In various examples, the techniques may include receiving first video data representing a scene in an environment. The techniques may further include generating illumination map data representing illumination of the scene in the first video data. The techniques may further comprise generating reflectance map data representing a reflectance of at least one object in the first video data. In some examples, the techniques may include sending, to a second computing device, the illumination map data and the reflectance map data. The techniques may further include receiving second video data representing the scene. The techniques may include determining a first illumination difference between the second video data and the first video data. The techniques may comprise sending, to the second computing device, the first illumination difference.
