# Instance Level Recognition

This repository contains the code for the 2nd place solution to the 2020 edition of the Landmark Recognition competition hosted by Google on Kaggle:

https://www.kaggle.com/c/landmark-recognition-2020/leaderboard

The full solution is described here

https://www.kaggle.com/c/landmark-recognition-2020/discussion/188299

## Definition
v2c(cleaned GLDv2), there are 1.6 million training images and 81k classes. All landmark test images belong to these classes.

v2x,in GLDv2, there are 3.2 million images belong to the 81k classes in v2c. I define these 3.2m images as v2x.

## Data preparation
1.Please config your local directory in CODE_DIR/src/config/config.py

2.Download Google Landmarks Dataset v2 train,test,index from https://github.com/cvdfoundation/google-landmark ,unpack them to DATA_DIR/images

3.Move train.csv,train_clean.csv to DATA_DIR/raw (provided by Kaggle, is not included in my solution file)

4.Download superpoint superglue models from https://github.com/magicleap/SuperPointPretrainedNetwork and https://github.com/magicleap/SuperGluePretrainedNetwork

5.Create split file:
```
python create_split.py
```
