# Controlnet - *Image Segmentation Version* |
|
|
|
ControlNet is a neural network structure to control diffusion models by adding extra conditions. |
|
This checkpoint corresponds to the ControlNet conditioned on **Image Segmentation**. |
|
|
|
It can be used in combination with [Stable Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/text2img). |

## Introduction |
|
|
|
Controlnet was proposed in [*Adding Conditional Control to Text-to-Image Diffusion Models*](https://arxiv.org/abs/2302.05543) by |
|
Lvmin Zhang, Maneesh Agrawala. |
|
|
|
The abstract reads as follows: |
|
|
|
*We present a neural network structure, ControlNet, to control pretrained large diffusion models to support additional input conditions. |
|
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). |
|
Moreover, training a ControlNet is as fast as fine-tuning a diffusion model, and the model can be trained on a personal devices. |
|
Alternatively, if powerful computation clusters are available, the model can scale to large amounts (millions to billions) of data. |
|
We report that large diffusion models like Stable Diffusion can be augmented with ControlNets to enable conditional inputs like edge maps, segmentation maps, keypoints, etc. |
|
This may enrich the methods to control large diffusion models and further facilitate related applications.* |
|
|
|
## Released Checkpoints |
|
|
|
The authors released 8 different checkpoints, each trained with [Stable Diffusion v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) |
|
on a different type of conditioning: |

## Example |
|
|
|
It is recommended to use the checkpoint with [Stable Diffusion v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) as the checkpoint |
|
has been trained on it. |
|
Experimentally, the checkpoint can be used with other diffusion models such as dreamboothed stable diffusion. |
|
|
|
1. Let's install `diffusers` and related packages: |
|
|
|
``` |
|
$ pip install diffusers transformers accelerate |
|
``` |
|
|
|
2. We'll need to make use of a color palette here as described in [semantic_segmentation](https://huggingface.co/docs/transformers/tasks/semantic_segmentation): |
|
|
|
```py |
|
palette = np.asarray([ |

3. Having defined the color palette we can now run the whole segmentation + controlnet generation code: |
|
|
|
```py |
|
from transformers import AutoImageProcessor, UperNetForSemanticSegmentation |
|

|

|

|
|
|
image = load_image("https://huggingface.co/lllyasviel/sd-controlnet-seg/resolve/main/images/house.png").convert('RGB') |
|
|
|
pixel_values = image_processor(image, return_tensors="pt").pixel_values |
|
|
|
with torch.no_grad(): |
|
outputs = image_segmentor(pixel_values) |
|
|
|
seg = image_processor.post_process_semantic_segmentation(outputs, target_sizes=[image.size[::-1]])[0] |
|
|
|
color_seg = np.zeros((seg.shape[0], seg.shape[1], 3), dtype=np.uint8) # height, width, 3 |
|
|
|
for label, color in enumerate(palette): |
|
color_seg[seg == label, :] = color |
|
|
|
color_seg = color_seg.astype(np.uint8) |
|
|
|
image = Image.fromarray(color_seg) |
|
|
|
controlnet = ControlNetModel.from_pretrained( |
|

|
) |
|
|
|
pipe = StableDiffusionControlNetPipeline.from_pretrained( |

|
) |
|
|
|
pipe.scheduler = UniPCMultistepScheduler.from_config(pipe.scheduler.config) |
|
|
|
# Remove if you do not have xformers installed |
|

|

|
|
|

|
|
|
image = pipe("house", image, num_inference_steps=20).images[0] |
|
|
|
image.save('./images/house_seg_out.png') |
|
``` |
|
|
|
 |
|
|
|
 |
|
|
|
 |
|
|
|
### Training |
|
|
|
The semantic segmentation model was trained on 164K segmentation-image, caption pairs from ADE20K. The model was trained for 200 GPU-hours with Nvidia A100 80G using Stable Diffusion 1.5 as a base model. |
