Hi Greg,

Local feature extractor is released here https://github.com/ducha-aiki/mods-light-zmq
Global CNN descriptor was trained by Anastasiia Mishchuk, I don`t have source code.
Fast KNN search was done pretty straightforward, based on example from faiss and I don`t think that I keep that part.
RANSAC part is here https://github.com/ducha-aiki/zeromqransac

And I don`t think that code for reading bunch of csv and save as submission has any value :)
