# FG-BMK Image Archive: FGVC-Aircraft

This repository stores the FGVC-Aircraft image archive used by FG-BMK. It is a companion repository for [SEU-VIPGroup/FG-BMK](https://huggingface.co/datasets/SEU-VIPGroup/FG-BMK), which contains the benchmark metadata, questions, splits, and evaluation code.

## Files

- `aircraft.zip`: image archive for the FGVC-Aircraft subset.

## Use with FG-BMK

1. Download `aircraft.zip`.
2. Extract it to a local data directory.
3. Use [SEU-VIPGroup/FG-BMK](https://huggingface.co/datasets/SEU-VIPGroup/FG-BMK) for the corresponding question files, class lists, train/test splits, and evaluation scripts.
4. Point the FG-BMK evaluation scripts to the extracted image folder.
