BRIA 2.3 ControlNet Canny Model Card

BRIA 2.3 ControlNet-Canny, 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 edge map from an input image. This allows for the creation of different variations of an image, all sharing the same geometry.
