Implementing Approximate Nearest Neighbor Search with KD-Trees

PyImageSearch

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. On Line 28 , we sort the distances and select the top k nearest neighbors.
