RenderMatte: Exact-Alpha Rendering and Group-Relative Alignment for Image Matting
The RenderMatte dataset is constructed, a large-scale synthetic dataset combining 3D-rendered RGBA foregrounds with diverse multi-source assets that features exact strand-level alpha annotations and diverse background composites, demonstrating a scalable path toward high-fidelity matting in open-world scenes.
