  • Trimming search space for nearest neighbor determinations in point cloud compression
    Patent number: 11699249
    Abstract: A search space for performing nearest neighbor searches for encoding point cloud data may be trimmed. Ranges of a space filling curve may be used to identify search space to exclude or reuse, instead of generating nearest neighbor search results for at least some of the points of a point cloud located within some of the ranges of the space filling curve. Additionally, neighboring voxels may be searched to identify any neighboring points missed during the trimmed search based on the ranges of the space filling curve.
    Type: Grant
    Filed: August 5, 2022
    Date of Patent: July 11, 2023
    Assignee: Apple Inc.
    Inventors: Khaled Mammou, Alexandros Tourapis, David Flynn, Zhenzhen Gao
