Detecting and Matching Related Objects with One Proposal Multiple Predictions

This repo is the implementation for Detecting and Matching Related Objects with One Proposal Multiple Predictions in CVPR 2021.

In this paper, we propose a simple yet efficient way to detect and match players and related objects at once without extra cost, by considering an implicit association for prediction of multiple objects through the same proposal box.

This repo cantains:

• Dataset generation for the proposed COCO +Torso dataset
• The model implementation & inference code

Demo

To visual validate the result for you can use demo.py to test the model in sample images.

usage: demo.py [-h] -m {fpn,fpn+mp} -c CHECKPOINT -i DEMO_FILE [-d]

optional arguments:
  -h, --help            show this help message and exit
  -m {fpn,fpn+mp}, --model {fpn,fpn+mp}
                        the model name
  -c CHECKPOINT, --checkpoint CHECKPOINT
                        optional checkpoint file
  -i DEMO_FILE, --demo-file DEMO_FILE
                        the address of the demo file
  -d, --display         whether display the detection result

For example,

# for regular detector
python -m demo -m fpn -c checkpoints/coco+torso/FPN_ResNet18_COCO_Torso_easy.pth -i images/COCO_val2014_000000022935.jpg

# for proposed detector with multiple prediction and matching
python -m demo -m fpn+mp -c checkpoints/coco+torso/FPN_MP_ResNet18_COCO_Torso_easy.pth -i images/COCO_val2014_000000022935.jpg
