Grassmannian Hashing
Grassmannian Hashing (GH) is an approximate nearest subspace search algorithm for solving the problem of retrieving similar subspaces via an approximation scheme called Locality Sensitive Hashing. For the detailed description of the algorithm and its numerical experiments, please refer to the ICCV paper below. For the justification of the algorithm and its underlying theory, please refer to the supplementary file.- Fast Subspace Search via Grassmannian Based Hashing, X. Wang, S. Atev, J. Wright and G. Lerman. ICCV (2013), Page 2776--2783, DOI 10.1109/ICCV.2013.345.
