# Background Removal

### Model Overview <a href="#model-overview" id="model-overview"></a>

**Background Removal** is a high-quality image segmentation model designed to isolate subjects from their background with precise, production-ready edge handling.

It delivers clean extractions across a wide range of photography scenarios, preserving fine details such as hair, soft edges, and semi-transparent elements. Well suited for both creative and high-volume image workflows, including product photography and e-commerce, flexible mask parameters enable further refinement for compositing, design, or downstream use.

### Key Capabilities <a href="#key-capabilities" id="key-capabilities"></a>

* Accurately separates subjects from backgrounds with clean, natural edge detail.
* Outputs both transparent background images and reusable masks for downstream workflows.
* User-adjustable mask controls including shrink/expand, feather, and invert for precise refinement.
