# Dataset Card for Action2MotionBehavior

<!-- Provide a quick summary of the dataset. -->

<!-- This dataset card aims to be a base template for new datasets. It has been generated using [this raw template](https://github.com/huggingface/huggingface_hub/blob/main/src/huggingface_hub/templates/datasetcard_template.md?plain=1). -->

Emotion-based dataset containing videos of 30 students from the Faculty of Mathematics and Computer Science, University of Bucharest, filming themselves expressing one of the six following basic emotions: anger, disgust, fear, happiness, sadness, surprise. The features of this dataset were extracted for the task of action-to-motion (A2M).

## Additional Repository Details

- "Feature Extraction" directory: the joints and poses extracted from each video of the dataset, following the SMPL and SMPL-X formats, along with labels (0-5 corresponding to anger-surprise). This was done with the help of the [HybrIK-X](https://github.com/jeffffffli/HybrIK) method, using the "HRNet-W48 + RLE" backbone. Moreover, each video was reformatted beforehand with the help of the FFmpeg command "ffmpeg -i input_path -vf scale=new_res -r 20 -c:v libx264 -preset ultrafast -crf 23 -an" where "new_res" was "iw/2:ih/2" if the video was filmed in 4K, or "iw:ih" otherwise
- "Model Training" directory: the model trained from scratch using only the features from the "Feature Extraction" directory, excluding the SMPL-X ones. This model is [MDM](https://github.com/GuyTevet/motion-diffusion-model)
