Open Remove Background Model (ormbg)

>>> DEMO <<<

Join our Research Discord Group!

This model is a fully open-source background remover optimized for images with humans. It is based on Highly Accurate Dichotomous Image Segmentation research. The model was trained with the synthetic Human Segmentation Dataset, P3M-10k, PPM-100 and AIM-500.

This model is similar to RMBG-1.4, but with open training data/process and commercially free to use.

Inference

python ormbg/inference.py

Training

Install dependencies:

conda env create -f environment.yaml
conda activate ormbg

Replace dummy dataset with training dataset.

python3 ormbg/train_model.py

Research

I started training the model with synthetic images of the Human Segmentation Dataset crafted with LayerDiffuse. However, I noticed that the model struggles to perform well on real images.

Synthetic datasets have limitations for achieving great segmentation results. This is because artificial lighting, occlusion, scale or backgrounds create a gap between synthetic and real images. A "model trained solely on synthetic data generated with naïve domain randomization struggles to generalize on the real domain", see PEOPLESANSPEOPLE: A Synthetic Data Generator for Human-Centric Computer Vision (2022).

Latest changes (05/07/2024):

Added P3M-10K dataset for training and validation
Added AIM-500 dataset for training and validation
Added PPM-100 dataset for training and validation
Applied Grid Dropout to make the model smarter

Next steps:

Expand dataset with synthetic and real images
Research on multi-step segmentation/matting by incorporating ViTMatte
