short_description: BiRefNet Background Removal on CPU
---

Runs `ibrhr/BiRefNet-openvino-xeon-w2145` OpenVINO models on CPU.

The Space accepts one uploaded image, lets the user choose a model variant, and returns:

- the predicted foreground mask
- a transparent PNG with the background removed
- processing time broken down by preprocessing, inference, and postprocessing
- runtime specs for the model variant, device, tensor shapes, and image size

Available OpenVINO variants:
