Abstract: Systems and methods are described for compressing color information in point cloud data. In some embodiments, point cloud data includes point position information and point color information for each of a plurality of points. The point position information is provided to a neural network, and the neural network generates predicted color information (e.g. predicted luma and chroma values) for respective points in the point cloud. A prediction residual is generated to represent the difference between the predicted color information and the input point color position. The point position information (which may be in compressed form) and the prediction residual are encoded in a bitstream. In some embodiments, color hint data is encoded to improve color prediction.

Abstract: Systems and methods are described for improved color rendering. In some embodiments, video is captured of a real-world scene, and a region of screen content is detected in the captured video. A processor selectively applies a screen-content color transformation on the region of screen content to generate processed video, and the processed video is displayed substantially in real time, for example on a video-see-through head-mounted display. The screen-content color processing may be different for different types of external displays. The screen-content color processing may also be determined based at least in part on illumination conditions. In some embodiments, the color of displayed virtual objects is adjusted based on visual parameters of the screen content.
