UniHuman

This repository provides the official code for CVPR 2024 paper UniHuman: A Unified Model For Editing Human Images in the Wild. This work was conducted during Nannan Li's Summer 2023 internship at Adobe Research.

1. Overview

This repo provides the source code for UniHuman, a model that leverages multiple data sources and connections between related tasks to achieve high-quality results across various human image editing objectives. For users who would like to try our pretrained model, please set up the environment according to Section 2: Environment Requirements, and run the program as instructed by Section 4: Gradio Demo and Section 5: Model Inference. For those who are interested in our collected data, please refer to Section 3: Data Preparation.

3. Data Preparation

We provide the image links of our dataset and their annotations in the zip files. See below for detailed instructions. Please note that we do not own the copyright of the images. It is solely your responsibility to check the original licenses of the images before using them. Any use of the images is at your own discretion and risk.

Dataset	No. of Train Images	No. of Test Pairs
WPose	N/A	2304
WVTON	N/A	440
LH-400K	409,270	N/A

3.1 Test Data

3.1.1 Reposing Dataset: WPose

Download the annotations wpose.zip and unzip it under the current directory.
Download the images using the links given in wpose/image_urls.txt and put them under ./downloaded_data. For your convenience, we provide a download script get_wpose_data.py. Running it will download and preprocess the raw images, but it is solely your responsibility to check the original licenses of the images before using them. Running the code will save the preprocessed images to ./wpose/images. In our preprocessing pipeline, we crop a rectangle centering the subject in the image and resize its longer side to 1024 pixels.

After the above steps, your directory structure should look like

downloaded_data
wpose
  ├── README
  ├── image_urls.txt
  ├── bbox.txt
  ├── test_pairs.txt
  ├── test_data.pkl
  ├── images
  ├── densepose
  ├── parsing
code
...

./downloaded_data: Downloaded original raw images. The images under this folder are no longer needed once the preprocessing is finished.

./wpose: Preprocessed images and annotations.

3.1.2 Tryon Dataset: WVTON

Download the annotations wvton.zip and unzip it under the current directory.
Download the clothing images in JPEG format manually using the urls provided in ./wvton/clothing_urls.txt. Put these clothing images in a new folder named ./cl_downloaded_data. Do NOT change the file names of the downloaded clothing images.
Download the human images using the links given in wvton/image_urls.txt and put them under ./downloaded_data. For your convenience, we provide a download script get_wvton_data.py. Running it will download and preprocess the raw images, but it is solely your responsibility to check the original licenses of the images before using them. Running the code will save the preprocessed images to ./wvton/images and ./wvton/clothes. In our preprocessing pipeline, we crop a rectangle in the image and resize its longer side to 1024 pixels.

After the above steps, your directory structure should look like

./downloaded_data: Downloaded original raw human images. The images under this folder are no longer needed once the preprocessing is finished.

./cl_downloaded_data: Downloaded original raw clothing images. The images under the folder are no longer needed once the preprocessing is finished.

./wvton: Preprocessed images and annotations.

3.1.3 Other Public Datasets

See VITON-HD, DressCode and DeepFashion-Multimodal.

3.2 Training Data

LH-400K

Download the annotations lh-400k.zip and unzip it under the current directory.
Download the images using the links given in wpose/image_urls.txt and put them under ./downloaded_data. For your convenience, we provide a download script get_laion_data.py. Running it will download and preprocess the raw images, but it is solely your responsibility to check the original licenses of the images before using them. Running the code will save the preprocessed images to ./lh-400k/images. In our preprocessing pipeline, we resize the image's longer side to 512 pixels.

After the above steps, your directory structure should look like

lh-400k
  ├── README
  ├── image_urls.txt
  ├── train_data.pkl
  ├── images
  ├── densepose
  ├── parsing
code
...

At the time of releasing this dataset, 408,520 image urls are still valid.

4. Gradio Demo

Please make sure that the required dependencies have been installed and your GPU memory is at least 16G.

Download the human parser checkpoint and put it under code/Graphonomy/.
Download pretrained models and unzip the file under the current directory.
Run
```
cd code
python demo.py
```
Go to http://0.0.0.0:7860 on your web browser. The webpage should look like below

To edit a human image, follow the steps below:

Upload source image -> Choose an editing task -> Click Confirm Task -> Upload target image -> Click Submit

It's suggested that your source and target image resolutions are at least 512 because we resize the input image's longer side to 512 pixels and then pad the shorter side to the same length. The generated image of size 512x512 will show on the top right. Intermediate outputs including detected pose and parsing will be displayed on the bottom right.

Section 5: Model Inference

We provide the model inference script code/infer.py for you to edit the input images in a folder. To use the script, please follow step 1 and 2 in Section 4: Gradio Demo to prepare the pretrained models.

Pose Transfer

Put the file paths to source images in source_img_paths.txt and the paths to target images in tgt_img_paths.txt. Then run

cd code
python infer.py  --task reposing --src-img-list source_img_paths.txt --tgt-img-list tgt_img_paths.txt  --out-dir ./results

Virtual Try-on

Put the file paths to source images in source_img_paths.txt and the paths to garment images in clothes_list.txt. Make sure the try-on garments belong to the same category (i.e., upper clothing, lower clothing or dress). Then run
```
cd code
python infer.py  --task tryon --src-img-list source_img_paths.txt --tgt-clothes-list clothes_list.txt --tryon-cat [upper/lower/dress] --out-dir ./results
```
Text Edit

Put the file paths to source images in source_img_paths.txt and the text prompts in prompt_list.txt. Make sure the garments you want to edit belong to the same category (i.e., upper clothing, lower clothing or dress). Then run
```
cd code
python infer.py  --task text_edit --src-img-list source_img_paths.txt --prompt-list prompt_list.txt --edit-cat [upper/lower/dress] --out-dir ./results --cfg_scale 4
```
To get the best results, you may want to try different values of --cfg_scale, which usually ranges from 1 to 10.

It's suggested that your source and target image resolutions are at least 512 because we resize the input image's longer side to 512 pixels and then pad the shorter side to the same length. The generated image is of size 512x512.
