Learning Super-Features for Image Retrieval

Fork from https://github.com/naver/FIRe, removing dependences of several submodules via adding these moudules to lib with path setting.

This repo is integrated to Hierarchical-Localization pipline by adding hloc/extractors/fire.py interface.

This repository contains the code for running FIRe model presented in our ICLR'22 paper:

Preparation

install ASMK

pip3 install pyaml numpy faiss-gpu 
cd lib/asmk
python3 setup.py build_ext --inplace
rm -r build

install dependencies by running:

pip3 install -r requirements.txt

data/experiments folders

All data will be stored under a folder fire_data that will be created when running the code; similarly, results and models from all experiments will be stored under folder fire_experiments

Evaluating our ICLR'22 FIRe model

To evaluate on ROxford/RParis our model trained on SfM-120k, simply run

python evaluate.py eval_fire.yml

With the released model and the parameters found in eval_fire.yml, we obtain 90.3 on the validation set, 82.6 and 62.2 on ROxford medium and hard respectively, 85.2 and 70.0 on RParis medium and hard respectively.

Training a FIRe model

Simply run

python train.py train_fire.yml -e train_fire

All training outputs will be saved to fire_experiments/train_fire.

To evaluate the trained model that was saved in fire_experiments/train_fire, simply run:

python evaluate.py eval_fire.yml -e train_fire -ml train_fire

Pretrained models

For reproducibility, we provide the following model weights for the architecture we use in the paper (ResNet50 without the last block + LIT):

Model pre-trained on ImageNet-1K (with Cross-Entropy, the pre-trained model we use for training FIRe) (link) or fire_imagenet.pth
Model trained on SfM-120k trained with FIRe (link) or fire_SfM_120k.pth

They will be automatically downloaded when running the training / testing script.
