Official pytorch implementation of the paper:
"An Edit Friendly DDPM Noise Space: Inversion and Manipulations"
Our inversion can be used for text-based editing of real images, either by itself or in combination with other editing methods.
Due to the stochastic nature of our method, we can generate diverse outputs, a feature that is not naturally available with methods relying on the DDIM inversion.
In this repository we support editing using our inversion, prompt-to-prompt (p2p)+our inversion, ddim or p2p (with ddim inversion).
our inversion: our ddpm inversion followed by generating an image conditioned on the target prompt.
prompt-to-prompt (p2p) + our inversion: p2p method using our ddpm inversion.
ddim: ddim inversion followed by generating an image conditioned on the target prompt.
p2p: p2p method using ddim inversion (original paper).
python -m pip install -r requirements.txt
This code was tested with python 3.8 and torch 2.0.0.
├── ddm_inversion - folder contains inversions in order to work on real images: ddim inversion as well as ddpm inversion (our method).
├── example_images - folder of input images to be edited
├── imgs - images used in this repository readme.md file
├── prompt_to_prompt - p2p code
├── main_run.py - main python file for real image editing
└── test.yaml - yaml file contains images and prompts to test on
A folder named 'results' will be automatically created and all the results will be saved to this folder. We also add a timestamp to the saved images in this folder.
Method's inputs:
init_img - the path to the input images
source_prompt - a prompt describing the input image
target_prompts - the edit prompt (creates several images if multiple prompts are given)
These three inputs are supplied through a YAML file (please use the provided 'test.yaml' file as a reference).
Method's parameters are:
skip - controlling the adherence to the input image
cfg_tar - classifier free guidance strengths
These two parameters have default values, as descibed in the paper.
python3 main_run.py --mode="our_inv" --dataset_yaml="test.yaml" --skip=36 --cfg_tar=15
python3 main_run.py --mode="p2pinv" --dataset_yaml="test.yaml" --skip=12 --cfg_tar=9
The mode argument can also be: ddim or p2p.
In our_inv and p2pinv modes we suggest to play around with skip in the range [0,40] and cfg_tar in the range [7,18].
p2pinv and p2p:
Note that you can play with the cross-and self-attention via --xa and --sa arguments. We suggest to set them to (0.6,0.2) and (0.8,0.4) for p2pinv and p2p respectively.
ddim and p2p:
skip is overwritten to be 0.
You can edit the test.yaml file to load your image and choose the desired prompts.
