# SynHairMan: Synthetic Video Matting Dataset

This repository contains the `SynHairMan` dataset, which was introduced in the paper [Generative Video Matting](https://huggingface.co/papers/2508.07905).

## Dataset Description

The `SynHairMan` dataset addresses the challenge of limited high-quality ground-truth data in video matting. It is a large-scale synthetic and pseudo-labeled segmentation dataset developed through a scalable data generation pipeline. This pipeline renders diverse human bodies and fine-grained hairs, yielding approximately 200 video clips, each with a 3-second duration.

The dataset is specifically designed for pre-training and fine-tuning video matting models, aiming to improve their generalization capabilities in real-world scenarios and ensuring strong temporal consistency by bridging the domain gap between synthetic and real-world scenes.
