Data-Free Class-Incremental Hand Gesture Recognition

Code and dataset for the ICCV 2023 paper:\ Data-Free Class-Incremental Hand Gesture Recognition\ S. Aich, J Ruiz-Santaquiteria, Z. Lu, P. Garg, K J Joseph, A. F. Garcia, V. N. Balasubramanian, K. Kin, C. Wan, N. C. Camgoz, S. Ma, and F De la Torre\ International Conference on Computer Vision (ICCV), 2023\ [project]

This (main) branch contains the implementation of the method proposed in this paper. Please refer to the baseline branch for the other DFCIL methods used for benchmarking.

Training

• Make sure the directories are correct for you in the ./scripts/common_dirs.sh file.

• Go to the corresponding scripts directory for a particular dataset:

  $ cd scripts/<DATASET>/mi_drop/supcon
  $ # <DATASET> is hgr_shrec_2017 or ego_gesture

• Run with a particular seed:

  $ ./all_runner_seed.sh <SEED> <GPU_ID>
  $ ./all_runner_seed.sh 0 1 # seed 0 gpu 1

• The accuracies with incremental class indices will be logged into the ./scripts//mi_drop/supcon/tmp directory.

• Good luck!

Datasets

• EgoGesture3D: The license for the EgoGesture3D skeletons are the same as this repository (license.txt). Please refer to the EgoGesture paper and the website for the original video dataset and corresponding license.
• SHREC-2017 train/val/test splits: This zip file only contains the split files comprising the list of files. Please refer to the SHREC 2017 website to download the dataset.
