# OneEmo: A Unified Multimodal Reasoning Model for Emotion Perception

This Space demonstrates [OneEmo](https://huggingface.co/Jiaha0Hu4ng/OneEmo), a unified
multimodal reasoning model for emotion perception, understanding, and interaction in
video scenarios. It supports eight tasks:

- **B-MER** – Basic Multimodal Emotion Recognition (single label)
- **MSA** – Multimodal Sentiment Analysis (positive/neutral/negative)
- **OV-MER** – Open-Vocabulary Multimodal Emotion Recognition
- **MHD** – Multimodal Humor Detection
- **MSD** – Multimodal Sarcasm Detection
- **ERG** – Empathetic Response Generation

Upload a video, select a task, and click **Analyze** to see the model's emotion
analysis with chain-of-thought reasoning.
