# Background Remover (BEN2 Base)
|
| 14 |
+
|
| 15 |
+
**BEN2 Base** is a deep learning model for **automatic background removal** from images.
|
| 16 |
+
The model predicts a **foreground segmentation mask** that can be used to remove or replace the background.
|
| 17 |
+
|
| 18 |
+
This repository contains the pretrained weights:
|
| 19 |
+
|
| 20 |
+
`BEN2_Base.pth`
|
| 21 |
+
|
| 22 |
+
The model can be used in:
|
| 23 |
+
|
| 24 |
+
- photo editing tools
|
| 25 |
+
- product image processing
|
| 26 |
+
- portrait segmentation
|
| 27 |
+
- dataset preprocessing
|
| 28 |
+
- AI image pipelines

Install required libraries:
|
| 57 |
+
|
| 58 |
+
```bash
|
| 59 |
+
pip install torch torchvision pillow numpy opencv-python
|
| 60 |
+
```

# Usage Example
|
| 65 |
+
|
| 66 |
+
Example inference using PyTorch.
|
| 67 |
+
|
| 68 |
+
```python
|
| 69 |
+
import torch
|
| 70 |
+
from PIL import Image
|
| 71 |
+
import torchvision.transforms as transforms
|
| 72 |
+
|
| 73 |
+
# Load model
|
| 74 |
+
model = torch.load("BEN2_Base.pth", map_location="cpu")
|
| 75 |
+
model.eval()
|
| 76 |
+
|
| 77 |
+
# Preprocessing
|
| 78 |
+
transform = transforms.Compose([
|
| 79 |
+
transforms.Resize((512, 512)),
|
| 80 |
+
transforms.ToTensor()
|
| 81 |
+
])
|
| 82 |
+
|
| 83 |
+
image = Image.open("input.jpg").convert("RGB")
|
| 84 |
+
input_tensor = transform(image).unsqueeze(0)
|
| 85 |
+
|
| 86 |
+
# Inference
|
| 87 |
+
with torch.no_grad():
|
| 88 |
+
output = model(input_tensor)
|
| 89 |
+
|
| 90 |
+
mask = output.squeeze().cpu().numpy()
|
| 91 |
+
```
|
| 92 |
+
|
| 93 |
+
You can apply the mask to generate a **transparent PNG** or replace the background.

# Example Workflow
|
| 98 |
+
|
| 99 |
+
1. Load an image
|
| 100 |
+
2. Resize and normalize
|
| 101 |
+
3. Run model inference
|
| 102 |
+
4. Generate segmentation mask
|
| 103 |
+
5. Remove background

# Limitations
|
| 124 |
+
|
| 125 |
+
- Performance may vary with extremely complex backgrounds.
|
| 126 |
+
- Very small foreground objects may reduce segmentation quality.
|
| 127 |
+
- Images should be resized for optimal results.
