BRIA-2.3-ControlNet-Background-Generation, Model Card
BRIA 2.3 ControlNet-Background Generation, trained on the foundation of BRIA 2.3 Text-to-Image, enables the generation of high-quality images guided by a textual prompt and the extracted background mask estimation from an input image. This allows for the creation of different background variations of an image, all sharing the same foreground.
BRIA 2.3 was trained from scratch exclusively on licensed data from our esteemed data partners.
