Abstract
In a point cloud attribute decoding method and device, Hilbert order is used as the coding order of point cloud attributes. The nearest neighbor points in the three-dimensional space of the current point are found in several points before the current point and are used as the prediction points of the current point. In the worst case, the distance in the three-dimensional space of the two points with a distance of n on the Hilbert order is less than or equal to n, while the distance in the three-dimensional space of the two points with a distance of n on the Morton order may be greater than the maximum dimension length of the point cloud. The average distance between K points in the preceding order and the current point in Hilbert sequence is smaller than that between K points in the preceding order and the current point in Morton sequence.
