This repo holds the official weights of BiRefNet_lite trained in 2K resolution.
Training Sets:
- DIS5K (except DIS-VD)
- HRS10K
- UHRSD
- P3M-10k (except TE-P3M-500-NP)
- TR-humans
- AM-2k
- AIM-500
- Human-2k (synthesized with BG-20k)
- Distinctions-646 (synthesized with BG-20k)
- HIM2K
- PPM-100
HR samples selection:
size_h, size_w = 1440, 2560
ratio = 0.8
h, w = image.shape[:2]
h >= size_h and w >= size_w or (h > size_h * ratio and w > size_w * ratio)
Validation Sets:
- DIS-VD
- TE-P3M-500-NP
