A method of point cloud attribute coding includes calculating a motion-estimating uncertainty value based on geometry data associated with a point cloud; identifying one or more inter-frame nearest neighbor point cloud samples corresponding to the point cloud in response to a determination that the motion-estimating uncertainty value is less than a threshold value; ranking one or more temporal candidate points associated with the one or more identified inter-frame nearest neighbor point cloud samples based on the motion-estimation uncertainty value; and extracting one or more sample attribute values from the one or more temporal candidate points, whereby the one or more sample attribute values correspond to the geometry data.
