# DragDiffusion
DragDiffusion 模型，利用扩散模型进行基于点的交互式图像编辑，允许用户将图像中的任意点“拖动”到目标位置，以精确控制姿势、形状、表情和布局。
## 论文
`DragDiffusion: Harnessing Diffusion Models for Interactive Point-based Image Editing`
- https://arxiv.org/abs/2306.14435
- CVPR 2024
## 模型结构
<!-- 此处一句话简要介绍模型结构 -->
<!-- DragDiffusion利用扩散模型进行基于点的交互式图像编辑。主要是基于 StyleGAN 模型架构： -->
<div align=center>
<img src="./doc/overview.png"/>
<div >DragDiffusion</div>
</div>
## 算法原理
DragDiffusion 算法受 DragGAN 的启发，把编解码的图像重建部分利用上大规模预训练扩散模型，极大提升了基于点的交互式编辑在现实世界场景中的适用性。
（1）先通过LoRA微调SD模型，数据集为用户输入的图像。目的是在编辑过程中（其实也是生成过程）更好的保留输入图像中物体和风格特征。\
（2）通过运动监督（Motion Supervision）和点跟踪（Point Tracking）实现对扩散 latent 进行优化，确保多步迭代过程中更加的精准和有效。\
（3）在最后一步去噪的过程中为了保证统一以及质量，从 MasaCtrl 中汲取灵感，提出利用自注意力模块的属性来引导去噪过程。
在编辑过程中，需要增加正则项确保非编辑区域（编辑mask区域外）不变。

## Installation
It is recommended to run our code on a Nvidia GPU with a linux system. We have not yet tested on other configurations. Currently, it requires around 14 GB GPU memory to run our method. We will continue to optimize memory efficiency
To install the required libraries, simply run the following command:
```
conda env create -f environment.yaml
conda activate dragdiff
```
## Run DragDiffusion
To start with, in command line, run the following to start the gradio user interface:
```
python3 drag_ui.py
```
You may check our [GIF above](https://github.com/Yujun-Shi/DragDiffusion/blob/main/release-doc/asset/github_video.gif) that demonstrate the usage of UI in a step-by-step manner.
Basically, it consists of the following steps:
### Case 1: Dragging Input Real Images
#### 1) train a LoRA
* Drop our input image into the left-most box.
* Input a prompt describing the image in the "prompt" field
* Click the "Train LoRA" button to train a LoRA given the input image
#### 2) do "drag" editing
* Draw a mask in the left-most box to specify the editable areas.
* Click handle and target points in the middle box. Also, you may reset all points by clicking "Undo point".
* Click the "Run" button to run our algorithm. Edited results will be displayed in the right-most box.
### Case 2: Dragging Diffusion-Generated Images
#### 1) generate an image
* Fill in the generation parameters (e.g., positive/negative prompt, parameters under Generation Config & FreeU Parameters).
* Click "Generate Image".
#### 2) do "drag" on the generated image
* Draw a mask in the left-most box to specify the editable areas
* Click handle points and target points in the middle box.
* Click the "Run" button to run our algorithm. Edited results will be displayed in the right-most box.
<!---
## Explanation for parameters in the user interface:
#### General Parameters
|Parameter|Explanation|
|-----|------|
|prompt|The prompt describing the user input image (This will be used to train the LoRA and conduct "drag" editing).|
|lora_path|The directory where the trained LoRA will be saved.|
#### Algorithm Parameters
These parameters are collapsed by default as we normally do not have to tune them. Here are the explanations:
* Base Model Config
|Parameter|Explanation|
|-----|------|
|Diffusion Model Path|The path to the diffusion models. By default we are using "botp/stable-diffusion-v1-5". We will add support for more models in the future.|
|VAE Choice|The Choice of VAE. Now there are two choices, one is "default", which will use the original VAE. Another choice is "stabilityai/sd-vae-ft-mse", which can improve results on images with human eyes and faces (see [explanation](https://stable-diffusion-art.com/how-to-use-vae/))|
* Drag Parameters
|Parameter|Explanation|
|-----|------|
|n_pix_step|Maximum number of steps of motion supervision. **Increase this if handle points have not been "dragged" to desired position.**|
|lam|The regularization coefficient controlling unmasked region stays unchanged. Increase this value if the unmasked region has changed more than what was desired (do not have to tune in most cases).|
|n_actual_inference_step|Number of DDIM inversion steps performed (do not have to tune in most cases).|
* LoRA Parameters
|Parameter|Explanation|
|-----|------|
|LoRA training steps|Number of LoRA training steps (do not have to tune in most cases).|
|LoRA learning rate|Learning rate of LoRA (do not have to tune in most cases)|
|LoRA rank|Rank of the LoRA (do not have to tune in most cases).|

## Common Issues and Solutions
1) For users struggling in loading models from huggingface due to internet constraint, please 1) follow this [links](https://zhuanlan.zhihu.com/p/475260268) and download the model into the directory "local\_pretrained\_models"; 2) Run "drag\_ui.py" and select the directory to your pretrained model in "Algorithm Parameters -> Base Model Config -> Diffusion Model Path".

# How to Evaluate with DragBench
### Step 1: extract dataset
Extract [DragBench](https://github.com/Yujun-Shi/DragDiffusion/releases/download/v0.1.1/DragBench.zip) into the folder "drag_bench_data".
Resulting directory hierarchy should look like the following:
<br>
drag_bench_data<br>
--- animals<br>
------ JH_2023-09-14-1820-16<br>
------ JH_2023-09-14-1821-23<br>
------ JH_2023-09-14-1821-58<br>
------ ...<br>
--- art_work<br>
--- building_city_view<br>
--- ...<br>
--- other_objects<br>
<br>
### Step 2: train LoRA.
Train one LoRA on each image in drag_bench_data.
To do this, simply execute "run_lora_training.py".
Trained LoRAs will be saved in "drag_bench_lora"
### Step 3: run dragging results
To run dragging results of DragDiffusion on images in "drag_bench_data", simply execute "run_drag_diffusion.py".
Results will be saved in "drag_diffusion_res".
### Step 4: evaluate mean distance and similarity.
To evaluate LPIPS score before and after dragging, execute "run_eval_similarity.py"
To evaluate mean distance between target points and the final position of handle points (estimated by DIFT), execute "run_eval_point_matching.py"
# Expand the Dataset
Here we also provided the labeling tool used by us in the file "labeling_tool.py".
Run this file to get the user interface for labeling your images with drag instructions.
