Inter prediction buffer generation for point cloud compression

Abstract

A device for processing point cloud data is configured to determine a first decoded frame of the point cloud data; generate, from points of the first decoded frame, a geometry reference buffer; generate, from the points of the first decoded frame, an attribute reference buffer that is separate from the geometry reference buffer and having an ordering of reference points in the attribute reference buffer is different than an ordering of reference points in the geometry reference buffer; determine a predicted geometry value for a point in a second decoded frame of the point cloud data from the geometry reference buffer; determine a predicted attribute value for the point in the second decoded frame of the point cloud data from the attribute reference buffer; and determine a final version of the second decoded frame of the point cloud data based on the predicted geometry value and the predicted attribute value.
