Automated high-quality background removal framework for an image using neural networks.

  • High Quality
  • Batch Processing
  • NVIDIA CUDA and CPU processing
  • FP16 inference: Fast inference with low memory usage
  • Easy inference
  • 100% remove.bg compatible FastAPI HTTP API
  • Removes background from hairs
  • Easy integration with your code

⛱ Try yourself on Google Colab

⛓️ How does it work?

It can be briefly described as

  1. The user selects a picture or a folder with pictures for processing
  2. The photo is preprocessed to ensure the best quality of the output image
  3. Using machine learning technology, the background of the image is removed
  4. Image post-processing to improve the quality of the processed image

🎓 Implemented Neural Networks:

Networks
Target
Accuracy

Tracer-B7 (default)
General (objects, animals, etc)
90% (mean F1-Score, DUTS-TE)

U^2-net
Hairs (hairs, people, animals, objects)
80.4% (mean F1-Score, DUTS-TE)

BASNet
General (people, objects)
80.3% (mean F1-Score, DUTS-TE)

DeepLabV3
People, Animals, Cars, etc
67.4% (mean IoU, COCO val2017)

Recommended parameters for different models

Notes:

  1. The final quality may depend on the resolution of your image, the type of scene or object.
  2. Use U2-Net for hairs and Tracer-B7 for general images and correct parameters.
    It is very important for final quality! Example images was taken by using U2-Net and FBA post-processing.

🖼️ Image pre-processing and post-processing methods:

🔍 Preprocessing methods:

  • none – No preprocessing methods used.

They will be added in the future.

  • none – No post-processing methods used.
  • fba (default) – This algorithm improves the borders of the image when removing the background from images with hair, etc. using FBA Matting neural network. This method gives the best result in combination with u2net without any preprocessing methods.

📦 Running the Framework / FastAPI HTTP API server via Docker:

Using the API via docker is a fast and non-complex way to have a working API.

Our docker images are available on Docker Hub.
Version tags are the same as the releases of the project with suffixes -cpu and -cuda for CPU and CUDA versions respectively.


Important Notes:

  1. Docker image has default front-end at / url and FastAPI backend with docs at /docs url.

  2. Authentication is enabled by default.
    Token keys are reset on every container restart if ENV variables are not set.
    See docker-compose.<device>.yml for more information.
    You can see your access keys in the docker container logs.

  3. There are examples of interaction with the API.
    See docs/code_examples/python for more details

🔨 Creating and running a container:

  1. Install docker-compose
  2. Run docker-compose -f docker-compose.cpu.yml up -d # For CPU Processing
  3. Run docker-compose -f docker-compose.cuda.yml up -d # For GPU Processing

Also you can mount folders from your host machine to docker container
and use the CLI interface inside the docker container to process
files in this folder.

Building a docker image on Windows is not officially supported. You can try using WSL2 or “Linux Containers Mode” but I haven’t tested this.

☑️ Testing

☑️ Testing with local environment

  1. pip install -r requirements_test.txt
  2. pytest

☑️ Testing with Docker

  1. Run docker-compose -f docker-compose.cpu.yml run carvekit_api pytest # For testing on CPU
  2. Run docker-compose -f docker-compose.cuda.yml run carvekit_api pytest # For testing on GPU
