VTG-GPT: Tuning-Free Zero-Shot Video Temporal Grounding with GPT

VTG-GPT

This is our implementation for the paper VTG-GPT: Tuning-Free Zero-Shot Video Temporal Grounding with GPT.

VTG-GPT leverages frozen GPTs to enable zero-shot inference without training.

• VTG-GPT
  • Preparation
  • Inference on QVHighlights val split
  • MiniGPT-v2 for Image captioning
  • Baichuan2 for Query debiasing

Preparation

1. Install dependencies

conda create -n vtg-gpt python=3.10
conda activate vtg-gpt
pip install -r requirements.txt

2. Unzip caption files

cd data/qvhighlights/caption/
unzip val.zip

Inference on QVHighlights val split

# inference
python infer_qvhighlights.py --val

# evaluation
bash standalone_eval/eval.sh

Run the above code to get:
