Installation

---

pip install -r requirements.txt

Preparing data

---

Edit config.data_tr in config.py to prepare data for different datasets.

python ./dump_data.py

Training

---

For the first time running main.py in each dataset, set the parameter initialize in Data_Loader to be True.

python ./main.py COLMAP #NARROW WIDE

End-to-end version

---

An end-to-end version has been released which is independent to affine information. Please refer to code/NM_Net_v2.py.
