Abstract
En 中文
• An improved inter-prediction method for point cloud compression is proposed.
• Eligibility check for prediction is refined using attribute residuals.
• Empty reference nodes are accurately interpolated using coplanar neighbors.
• The proposed approach yields significant bitrate savings for color attributes.
