BodyHands

This repository contains the code and data for the following paper:

Whose Hands Are These? Hand Detection and Hand-Body Association in the Wild (CVPR 2022)

We develop a method to detect hands and their corresponding body locations. Hands and bodies belonging to the same person have bounding boxes in the same color and identification numbers

Installation

Follow the installation instructions in INSTALL.md.

Project Page and Data

Please see the project page for the required dataset and annotation format.

Models

Download models and place them in ./models/.

Training

Use the following command for training:

python train_net.py --config-file configs/BodyHands.yaml

Evaluation

Use the following command for evaluation:

python train_net.py --config-file configs/BodyHands.yaml --eval-only MODEL.WEIGHTS <path to model weights>

Demo: Run hand detection and hand-body association on custom images

Use the following command to detect hands and their corresponding person locations:

python demo.py --input <path to a directory containing images> --thresh 0.7

Use the parameter thresh to vary the precision and recall of detections.

The output images with hand detections and corresponding body locations' visualizations will be stored in ./demoOutput/.
