 This repository follows the method from ["YouTube-ASL: A Large-Scale, Open-Domain American Sign Language-English Parallel Corpus" (Uthus et al., 2023)](https://arxiv.org/abs/2306.15162) which is designed to handle both **YouTube-ASL** and **How2Sign** datasets through **MediaPipe Holistic**. Our pipeline streamlines the workflow from video acquisition to landmark extraction, preparing the data for ASL translation tasks.
