      - extract features now returns receptive field centers · 80b5805c

      - wrote matching function (currently ransac runs on cpu single core - kinda slow, kd tree is multithreaded and fast)
      - matching works, tested on one of the query images, returns itself first, then the query images that show similar content then a few others rest is rejected
      
      Todos: matching parameters (thresholds, trails etc. need estimation)
      clean up
      incorperate into experiment structure
      process output information

      oxford_sorter.py is experimental. Mostly used it to get the index set but have to understand the dataset better before building it.
      - removed extract_features function form util -> model can now get all features per image, experiment manager will run retrieval/ data loading
      - added custom dataset to dataloader.py that also returns filepaths
      - perform retrieval so far extracts index features and performs pca
      
      note: pca in test run only explains ~40% of variance. is that feasible?
      
      TODO: extract features should return rf centers instead of boxes
      write matching function
      incorporate it into experiment manager

      Started writing retrieval code. · d6031024

      Accumulating data from scales pyramid
      calculate receptive fields for each feature
      perform nms based on scores and receptive field boxes and keeping the topk per image
      tested running pca
      
      TODO: Find out what info we need to keep for real retrieval (image class or id?)
      Do we have multiple photos of the same landmark in our database???
