Quick Start

pip install lama-cleaner

# Model will be downloaded automatically
lama-cleaner --model=lama --device=cpu --port=8080
# Lama Cleaner is now running at http://localhost:8080

Available arguments:

Name Description Default
--model lama/ldm/zits. See details in Inpaint Model lama
--device cuda or cpu cuda
--port Port for backend flask web server 8080
--gui Launch lama-cleaner as a desktop application
--gui_size Set the window size for the application 1200 900
--input Path to image you want to load by default None
--debug Enable debug mode for flask web server

Inpainting Model

Model Description Config
LaMa 👍 Generalizes well on high resolutions(~2k)
LDM 👍 Possiblablity to get better and more detail result
👍 The balance of time and quality can be achieved by adjusting steps
😐 Slower than GAN model
😐 Need more GPU memory
Steps: You can get better result with large steps, but it will be more time-consuming
Sampler: ddim or plms. In general plms can get better results with fewer steps
ZITS 👍 Better holistic structures compared with previous methods
😐 Wireframe module is very slow on CPU
Wireframe: Enable edge and line detect
MAT TODO

LaMa vs ZITS

Image is from ZITS paper. I didn't find a good example to show the advantages of ZITS and let me know if you have a good example. There can also be possible problems with my code, if you find them, please let me know too!

High Resolution Strategy

There are three strategies for handling high-resolution images.

  • Original: Use the original resolution of the picture, suitable for picture size below 2K.
  • Resize: Resize the image to a smaller size, then do inpainting on the resized image. The inpainting area will be croped, upsampled and pasted back on the original image to make sure other part of image not loss quality.
  • Crop: Crop masking area from the original image to do inpainting, and paste the result back. Mainly for performance and memory reasons on high resolution image.

Download Model Mannually

If you have problems downloading the model automatically when lama-cleaner start, you can download it manually. By default lama-cleaner will load model from TORCH_HOME=~/.cache/torch/hub/checkpoints/, you can set TORCH_HOME to other folder and put the models there.

Development

Only needed if you plan to modify the frontend and recompile yourself.

Frontend

Frontend code are modified from cleanup.pictures, You can experience their great online services here.

  • Install dependencies:cd lama_cleaner/app/ && yarn
  • Start development server: yarn start
  • Build: yarn build

Docker

Run within a Docker container. Set the CACHE_DIR to models location path. Optionally add a -d option to the docker run command below to run as a daemon.

Build Docker image

docker build -f Dockerfile -t lamacleaner .

Run Docker (cpu)

docker run -p 8080:8080 -e CACHE_DIR=/app/models -v  $(pwd)/models:/app/models -v $(pwd):/app --rm lamacleaner python3 main.py --device=cpu --port=8080

Run Docker (gpu)

docker run --gpus all -p 8080:8080 -e CACHE_DIR=/app/models -v $(pwd)/models:/app/models -v $(pwd):/app --rm lamacleaner python3 main.py --device=cuda --port=8080

Then open http://localhost:8080
