Precision-recall curves for retrieval tasks. 2-NN-GV: BoI vectors are obtained with two nearest neighbor search followed by geometric verification; 5-NN-GV: 5 nearest neighbor search followed by geometric verification; 2-NN, 5-NN: nearest neighbor search without geometric verification. Geometric verification is critical for accurate retrieval. a Precison-recall for video retrieval on BoI vectors. b Precison-Recall for video retrieval on binary BoI vectors
