Implementing Approximate Nearest Neighbor Search with KD-Trees
PyImageSearch
DECEMBER 23, 2024
Traditional exact nearest neighbor search methods (e.g., brute-force search and k -nearest neighbor (kNN)) work by comparing each query against the whole dataset and provide us the best-case complexity of. Figure 1: Example of a 2-dimensional KD-tree (source: Warnasooriya, Medium , 2024 ).
