Model by Lyumin Zhang

Usage

Input an image, and prompt the model to generate an image as you would for Stable Diffusion. Then. a model called Uniformer will detect the segmentations for you to control your output image.

Model Description

This model is ControlNet adapting Stable Diffusion to use a semantic segmentation of an input image in addition to a text input to generate an output image. The segmentation model will first segment the input image into different semantic regions, and then use those regions as conditioning input when generating a new image. This model was trained with the ADE20K dataset captioned by BLIP to obtain 164K segmentation-image-caption pairs. The model is trained with 200 GPU-hours on Nvidia A100 80G. The base model is Stable Diffusion 1.5.

ControlNet is a neural network structure which allows control of pretrained large diffusion models to support additional input conditions beyond prompts. The ControlNet learns task-specific conditions in an end-to-end way, and the learning is robust even when the training dataset is small (< 50k samples). Moreover, training a ControlNet is as fast as fine-tuning a diffusion model, and the model can be trained on a personal device. Alternatively, if powerful computation clusters are available, the model can scale to large amounts of training data (millions to billions of rows). Large diffusion models like Stable Diffusion can be augmented with ControlNets to enable conditional inputs like edge maps, segmentation maps, keypoints, etc.

Other ControlNets

There are many different ways to use a ControlNet to modify the output of Stable Diffusion. Here are a few different options, all of which use an input image in addition to a prompt to generate an output. The methods process the input in different ways; try them out to see which works best for a given application.
