Setup

Please see installation for details.

Quick Start

Google Colab demo for GVHMR

HuggingFace demo for GVHMR

Demo

Demo entries are provided in tools/demo. Use -s to skip visual odometry if you know the camera is static, otherwise the camera will be estimated by DPVO. We also provide a script demo_folder.py to inference a entire folder.

python tools/demo/demo.py --video=docs/example_video/tennis.mp4 -s
python tools/demo/demo_folder.py -f inputs/demo/folder_in -d outputs/demo/folder_out -s

Reproduce

  1. Test: To reproduce the 3DPW, RICH, and EMDB results in a single run, use the following command:

    python tools/train.py global/task=gvhmr/test_3dpw_emdb_rich exp=gvhmr/mixed/mixed ckpt_path=inputs/checkpoints/gvhmr/gvhmr_siga24_release.ckpt

    To test individual datasets, change global/task to gvhmr/test_3dpw, gvhmr/test_rich, or gvhmr/test_emdb.

  2. Train: To train the model, use the following command:

    # The gvhmr_siga24_release.ckpt is trained with 2x4090 for 420 epochs, note that different GPU settings may lead to different results.
python tools/train.py exp=gvhmr/mixed/mixed

    During training, note that we do not employ post-processing as in the test script, so the global metrics results will differ (but should still be good for comparison with baseline methods).
