# Salient Object Aware Background Generation [](https://arxiv.org/pdf/2404.10157.pdf)
This repository accompanies our paper, [Salient Object-Aware Background Generation using Text-Guided Diffusion Models](https://arxiv.org/abs/2404.10157), which has been accepted for publication in [CVPR 2024 Generative Models for Computer Vision](https://generative-vision.github.io/workshop-CVPR-24/) workshop.
The paper addresses an issue we call "object expansion" when generating backgrounds for salient objects using inpainting diffusion models. We show that models such as [Stable Inpainting](https://huggingface.co/stabilityai/stable-diffusion-2-inpainting) can sometimes arbitrarily expand or distort the salient object, which is undesirable in applications where the object's identity should be preserved, such as e-commerce ads. We provide some examples of object expansion as follows:

## Setup
The dependencies are provided in `requirements.txt`, install them by:
```bash
pip install -r requirements.txt
```
## Usage
### Training
The following runs the training of text-to-image inpainting ControlNet initialized with the weights of "stable-diffusion-2-inpainting":
```bash
accelerate launch --multi_gpu --mixed_precision=fp16 --num_processes=8 train_controlnet_inpaint.py --pretrained_model_name_or_path "stable-diffusion-2-inpainting" --proportion_empty_prompts 0.1
```
The following runs the training of text-to-image ControlNet initialized with the weights of "stable-diffusion-2-base":
```bash
accelerate launch --multi_gpu --mixed_precision=fp16 --num_processes=8 train_controlnet.py --pretrained_model_name_or_path "stable-diffusion-2-base" --proportion_empty_prompts 0.1
```
### Inference
Please refer to `inference.ipynb`. Tu run the code you need to download our model checkpoints.
