Controlnet
Controlnet is an auxiliary model which augments pre-trained diffusion models with an additional conditioning.
Controlnet comes with multiple auxiliary models, each which allows a different type of conditioning
Controlnet's auxiliary models are trained with stable diffusion 1.5. Experimentally, the auxiliary models can be used with other diffusion models such as dreamboothed stable diffusion.
The auxiliary conditioning is passed directly to the diffusers pipeline. If you want to process an image to create the auxiliary conditioning, external dependencies are required.
Some of the additional conditionings can be extracted from images via additional models. We extracted these additional models from the original controlnet repo into a separate package that can be found on github.

Training
The hough line model was trained on 600k edge-image, caption pairs. The dataset was generated from Places2 using BLIP to generate text captions and a deep Hough transform to generate edge-images. The model was trained for 160 GPU-hours with Nvidia A100 80G using the Canny model as a base model.
