We have also released the Emotion-Gait dataset with this code, which is available for download here: https://go.umd.edu/emotion-gait.

1. generator_cvae is the generator.

2. classifier_stgcn_real_only is the baseline classifier using only the real 342 gaits.

3. classifier_stgcn_real_and_synth is the baseline classifier using both real 342 and N synthetic gaits.

4. clasifier_hybrid is the hybrid classifier using both deep and physiologically-motivated features.

5. compute_aff_features consists of the set of scripts to compute the affective features from 16-joint pose sequences. Calling main.py with the correct data path computes the features, and save them in the affectiveFeatures<f_type>.h5 file, where f_type is the desired type of features:

   • '' original data (default)
   • 4DCVAEGCN data generated by the CVAE.
