PRVQ provides an approximate solution for fast nearest neighbor search and reduces the memory constraints significantly for storing the EVLAD descriptors by encoding them into compact code.
Column 4 and column 5 of Table 1 show the relative improvement of EVLAD when applying dimensionality reduction and using compact codes obtained by PRVQ [23].
