ObjectBox: From Centers to Boxes for Anchor-Free Object Detection

ECCV 2022 (Oral Presentation)

Dependencies

PyTorch

This code is tested under Ubuntu 18.04, CUDA 11.2, with one NVIDIA Titan RTX GPU.
Python 3.8.8 version is used for development.

Preparation

Set the 'PATH' in '/data/coco.yaml' and '/data/VOC.yaml'
Set the 'project' flag in flag_sets.py

Training

Set 'task' flag in flag_sets.py as: 'train'

For MS-COCO 2017 experiments, set:
exp = 'coco'
in flag_sets.py

For PASCAL VOC 2012 experiments, set:
exp = 'pascal'
in flag_sets.py

Run train.py

Test

Set 'task' flag in flag_sets.py as: 'test'

Run val.py
