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

Performance:

Check the main BiRefNet model repo for more info and how to use it:
