Abstract
Aspects of the disclosure provide methods and apparatuses for point cloud compression. In some examples, an apparatus for point cloud compression includes processing circuitry. In some embodiments, the processing circuitry determines one or more original points in a point cloud that are associated with a reconstructed position. Positions of the one or more original points can be reconstructed, according to a geometry quantization, to the reconstructed position. The processing circuitry then determines an attribute value for the reconstructed position based on attribute information of the one or more original points, and encodes texture of the point cloud with the reconstructed position having the determined attribute value.
