Assumptions and limitations
This is a color-key background remover, NOT an AI background segmentation model. Complex hair, shadows, patterned backgrounds and similarly colored foregrounds may be damaged.
Frequently asked questions
Can this remove detailed backgrounds like AI does?
No. This works best on clean, uniform backgrounds and cannot reliably segment complex objects.
