I will first give a brief overview of recent works in image indexing and fast matching, following the Bag-Of-Words framework.
Next I’ll use the following two papers as examples.
J. Philbin, O. Chum, M. Isard, J. Sivic, and A. Zisserman, Object retrieval with large vocabularies and fast spatial matching, in Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition, 2007.
O. Chum, J. Philbin, and A. Zisserman, Near duplicate image detection: min-hash and tf-idf weighting, in Proceedings of the British Machine Vision Conference, 2008.
