About reproduce the results in the paper about patch-netvlad

Hi @CaiYingFeng, the results in Table 2 are all done using WPCA4096. The only results that use WPCA512 in the paper are those in Figure 4. Try running Single Spatial but with WPCA4096 and that should fix the numbers. As to Spatial being better than RANSAC, we did notice that can happen in some datasets.

Also, in addition to Stephen's comments, we re-trained the network for the public code release and there might be minor deviations in the results obtained using the new network with those from what is reported in the paper (we checked that they are generally <1% difference in recall, sometimes they are slightly better than what is reported in the paper, sometimes slightly worse).

Feel free to re-open if you have further questions @CaiYingFeng.
