My PyTorch Implementation of DeLF #1

Hi, I found your repo, and just uploaded the code DeLF training code I implemented. (I've done this project quite long time ago, but was lazy enough to upload it on github...)
Refer to the code, It may be helpful for your implementation :)
Hope you enjoy the code! Thanks.

Cool implementation. I think Delf is interesting for research but not practical for engineering because of the time consuming geometry verification.

yeah, that's true. But we can solve it by scaling out supported by enough amount of computing power, and careful choice of inference parameters.
But in order to use DeLF in real service, we need to assume the N candidates are already chosen using certain algorithm. Bruteforce searching 1000 candidates for each localfeature from whole gallary is extremely expensive.
