FeyNoBg - SOTA automatic background removal model and training library

FeyNoBg is a state-of-the-art AI model for automatic background removal, delivering top-tier performance across eight industry benchmarks. It excels in complex scenarios like low contrast, camouflage, and high-resolution 4K/8K images by balancing precise foreground recognition with detailed boundary tracing. Accompanying the model is NoBg, an open-source Python library that simplifies running FeyNoBg or training custom models with a consistent, high-performance interface. Built on BiRefNet and trained on diverse datasets, this toolkit empowers developers to achieve professional-grade image matting effortlessly.

Real images are complex and require deftness in foreground recognition and boundary precision. This was our key insight when training FeyNoBg.

    I love seeing this. Background removal is such a core task used in so many systems, I group it in with speech to text in terms of importance.

    I love seeing maturity getting pushed in this space. Congratulations to you and the team!

    How does it stack up against Adobe's model? The advantage Adobe has is there are essentially two options: (1) Select Subject (95% of the time will give you the result you want); (2) Select Person (helps in the edge cases).

    The issue I have is, what is the subject? For instance, you have a person sat on a couch. You hit Select Subject. Is the subject the person, or the person plus the couch?

    With Adobe's when I only want the person, most of the time Select Subject works, and when it doesn't I can pivot to Select Person, but that has its own problem because it won't include props that the subject is holding, only the person and their clothing.

    Why extend an MIT licensed model's weights (BiRefNet) and release it under a cc-by-nc-4.0 license?
