Product quantization for nearest neighbor search - Inria

expected squared distance, which is required for "-radius search or for using Lowe’s distance ratio criterion [23]. The motivation of using the Hamming space in [20], [17], [19] is to compute distances efficiently. Note, how-ever, that one of the fastest ways to compute Hamming distances consists in using table lookups. Our method
