(ECCV 22 Oral) ObjectBox: From Centers to Boxes for Anchor-Free Object Detection

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
