FeyNoBg (RMBG) is a ComfyUI node in the 🧪AILab/🧽RMBG category from ComfyUI-RMBG. Inputs: image, mask_blur, mask_offset, invert_output. Outputs: IMAGE, MASK…

A sophisticated ComfyUI custom node engineered for advanced image background removal and precise segmentation of objects, faces, clothing, and fashion elements. This tool leverages a diverse array of models, including RMBG-2.0, INSPYRENET, BEN, BEN2, BiRefNet models, SAM, and GroundingDINO, while also incorporating a new feature for real-time background replacement and enhanced edge detection for improved accuracy.
