BRIA Background Removal v2.0 Model Card

💜 Bria AI | 🤗 Hugging Face | 📑 Blog
🖥️ Demo | Github

RMBG v2.0 is our new state-of-the-art background removal model significantly improves RMBG v1.4. The model is designed to effectively separate foreground from background in a range of categories and image types. This model has been trained on a carefully selected dataset, which includes: general stock images, e-commerce, gaming, and advertising content, making it suitable for commercial use cases powering enterprise content creation at scale. The accuracy, efficiency, and versatility currently rival leading source-available models. It is ideal where content safety, legally licensed datasets, and bias mitigation are paramount.

Developed by BRIA AI, RMBG v2.0 is available as a source-available model for non-commercial use.

Model Details

Model Description

Developed by: BRIA AI
Model type: Background Removal
License: Creative Commons Attribution–Non-Commercial (CC BY-NC 4.0)

- Commercial use is subject to a commercial agreement with BRIA. Available here
Model Description: BRIA RMBG-2.0 is a dichotomous image segmentation model trained exclusively on a professional-grade dataset. The model output includes a single-channel 8-bit grayscale alpha matte, where each pixel value indicates the opacity level of the corresponding pixel in the original image. This non-binary output approach offers developers the flexibility to define custom thresholds for foreground-background separation, catering to varied use cases requirements and enhancing integration into complex pipelines.

Training data

Bria-RMBG model was trained with over 15,000 high-quality, high-resolution, manually labeled (pixel-wise accuracy), fully licensed images. Our benchmark included balanced gender, balanced ethnicity, and people with different types of disabilities. For clarity, we provide our data distribution according to different categories, demonstrating our model’s versatility.

Distribution of images:

Category	Distribution
Objects only	45.11%
People with objects/animals	25.24%
People only	17.35%
people/objects/animals with text	8.52%
Text only	2.52%
Animals only	1.89%

Category	Distribution
Photorealistic	87.70%
Non-Photorealistic	12.30%

Category	Distribution
Non Solid Background	52.05%
Solid Background	47.95%

Category	Distribution
Single main foreground object	51.42%
Multiple objects in the foreground	48.58%

Usage

from PIL import Image
import torch
from torchvision import transforms
from transformers import AutoModelForImageSegmentation

device = 'cuda' if torch.cuda.is_available() else 'cpu'
model = AutoModelForImageSegmentation.from_pretrained('briaai/RMBG-2.0', trust_remote_code=True).eval().to(device)

# Data settings
image_size = (1024, 1024)
transform_image = transforms.Compose([
    transforms.Resize(image_size),
    transforms.ToTensor(),
    transforms.Normalize([0.485, 0.456, 0.406], [0.229, 0.224, 0.225])
])

image = Image.open(input_image_path)
input_images = transform_image(image).unsqueeze(0).to(device)

# Prediction
with torch.no_grad():
    preds = model(input_images)[-1].sigmoid().cpu()
pred = preds[0].squeeze()
pred_pil = transforms.ToPILImage()(pred)
mask = pred_pil.resize(image.size)
image.putalpha(mask)

image.save("no_bg_image.png")
