Feyn公司推出了FeyNoBg，一套用于自动背景移除的AI模型系统，并同步开源了支撑该模型的Python库NoBg 1。FeyNoBg采用可解释性优先的训练方法，在来自10个数据集的26.1K多样化示例上进行训练 1。
该模型在八个基准测试中表现突出，其中四项取得最佳成绩，其余成绩均在最优值的2%以内 1。技术实现上，FeyNoBg通过扩展BiRefNet架构第三阶段的block数量（从18增至24）实现性能提升 1。NoBg库集成了图像matting模型的完整工作流，涵盖预处理、训练和评估环节，目前支持BiRefNet架构 1。
Feyn has unveiled FeyNoBg, an artificial intelligence model designed for automatic background removal, alongside the release of NoBg, an open-source Python library for training and deploying the system 1. The model was developed using an interpretability-first training methodology and trained on a diverse dataset comprising 26.1 thousand examples drawn from ten different sources 1.
The FeyNoBg model demonstrated strong performance across multiple benchmarks, achieving top results on four of eight evaluation tests, with the remaining scores falling within 2 percent of the best performance 1. The underlying technical architecture extends BiRefNet's third stage from 18 blocks to 24 blocks to enhance the model's capabilities 1. The NoBg library integrates the complete workflow for image matting models, encompassing preprocessing, training, and evaluation stages, and currently supports the BiRefNet architecture 1.
The model is available through Hugging Face at https://huggingface.co/spaces/feyninc/feynobg, while the source code for the NoBg library can be accessed on GitHub at https://github.com/feyninc/nobg 1.
