OpenGlottal: GIRAFE-trained U-Net (Crop Mode)

This repository contains the pre-trained U-Net weights (og_girafe_unet_crop.pt) for glottal area segmentation, as presented in the paper: A Detection-Gated Pipeline for Robust Glottal Area Waveform Extraction and Clinical Pathology Assessment.

This model is part of the OpenGlottal toolkit, an open-source framework designed for automated glottal area segmentation from high-speed videoendoscopy (HSV). This specific checkpoint was trained on the GIRAFE dataset using the "YOLO-Crop+UNet" strategy, where a detector localizes the glottis to provide a tight crop for the U-Net, ensuring higher effective resolution.

How to use

You can download the U-Net weights and run displacement extraction using the openglottal toolkit.

Download Weights

from huggingface_hub import hf_hub_download
unet_path = hf_hub_download(repo_id="hari-krishnan-u/og_girafe_unet_crop", filename="og_girafe_unet_crop.pt")

Run Inference (CLI)

To run displacement extraction in Left/Right (LR) mode:

openglottal displacement /path/to/video.avi \
  --unet-weights "$unet_path" \
  --start 0 --end 500 \
  --mode lr \
  --lr-position 0.5 \
  --output results/
