# Super-Resolution with Perturbed-Attention Guidance
[Project](https://ku-cvlab.github.io/Perturbed-Attention-Guidance/) / [arXiv](https://arxiv.org/abs/2403.17377) / [GitHub](https://github.com/KU-CVLAB/Perturbed-Attention-Guidance)
This repository is based on [Diffusers](https://huggingface.co/docs/diffusers/index).
[ControlNet](https://arxiv.org/abs/2302.05543) is a neural network structure to control diffusion models by adding extra conditions. The pipeline is a modification of StableDiffusionControlNetPipeline to support image generation with ControlNet and Perturbed-Attention Guidance (PAG).
In addition to the examples provided with Openpose, you can also generate using various conditions. Please refer to "ControlNet" section of an [official document](https://huggingface.co/docs/diffusers/using-diffusers/controlnet) for details.
## Quickstart
Loading ControlNet and Custom Piepline:
```
from diffusers import ControlNetModel, StableDiffusionControlNetPipeline
controlnet = ControlNetModel.from_pretrained(
"lllyasviel/sd-controlnet-openpose",
torch_dtype=torch.float16
)
pipe = StableDiffusionControlNetPipeline.from_pretrained(
"runwayml/stable-diffusion-v1-5",
custom_pipeline="hyoungwoncho/sd_perturbed_attention_guidance_controlnet",
controlnet=controlnet,
torch_dtype=torch.float16
)
device="cuda"
pipe = pipe.to(device)
```
Prepare Conditional Images:
```
from controlnet_aux import OpenposeDetector
openpose = OpenposeDetector.from_pretrained("lllyasviel/ControlNet")
original_image = load_image(
"https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/person.png"
)
openpose_image = openpose(original_image)
prompts=""
```
Conditional Generation with ControlNet and PAG:
```
output = pipe(
prompts,
image=openpose_image,
num_inference_steps=50,
guidance_scale=0.0,
pag_scale=4.0,
pag_applied_layers_index=["m0"]
).images[0]
```
## Parameters
guidance_scale : gudiance scale of CFG (ex: 7.5)
pag_scale : gudiance scale of PAG (ex: 4.0)
pag_applied_layers_index : index of the layer to apply perturbation (ex: ['m0']) |
