SUMMARY:Manifold k-NN: Accelerated k-NN Queries for Manifold Point Clouds
DESCRIPTION:Pengfei Wang, Qinghao Guo, Haisen Zhao, and Shiqing Xin (Shand
 ong University); Shuangmin Chen (Qingdao University of Science and Technol
 ogy); Changhe Tu (Shandong University); and Wenping Wang (Texas A&M Univer
 sity)\n\nWe present Manifold k-NN, a dynamic programming-based framework f
 or accelerated k-nearest neighbor search on manifold point clouds. By recu
 rsively partitioning insertion history via Voronoi successor lists, our me
 thod achieves 1–10× speedup over kd-trees in volume-to-surface queries, wh
 ile supporting zero-overhead prefix queries and dynamic point deletion.\n\
