CVAT is completely re-designed and re-implemented version of Video Annotation Tool from Irvine, California tool. It is free, online, interactive video and image annotation tool for computer vision. It is being used by our team to annotate million of objects with different properties. Many UI and UX decisions are based on feedbacks from professional data annotation team.

Onepanel has added CVAT as an environment into their platform and a running demo of CVAT can be accessed at CVAT Public Demo.

After you click the link above:

• Click on "GO TO WORKSPACE" and the CVAT environment will load up
• The environment is backed by a K80 GPU

If you have any questions, please contact Onepanel directly at [email protected]. If you are in the Onepanel application, you can also use the chat icon in the bottom right corner.

The instructions below should work for Ubuntu 16.04. It will probably work on other Operating Systems such as Windows and macOS, but may require minor modifications.

Please read official manual here.

sudo pip install docker-compose

To build all necessary docker images run docker-compose build command. By default, in production mode the tool uses PostgreSQL as database, Redis for caching.

To start default container run docker-compose up -d command. Go to localhost:8080. You should see a login page.

# Build image with CUDA and OpenVINO support
docker-compose -f docker-compose.yml -f components/cuda/docker-compose.cuda.yml -f components/openvino/docker-compose.openvino.yml build

# Run containers with CUDA and OpenVINO support
docker-compose -f docker-compose.yml -f components/cuda/docker-compose.cuda.yml -f components/openvino/docker-compose.openvino.yml up -d

• Auto annotation using DL models in OpenVINO toolkit format
• Analytics: management and monitoring of data annotation team
• TF Object Detection API: auto annotation
• Support for NVIDIA GPUs

You can register a user but by default it will not have rights even to view list of tasks. Thus you should create a superuser. The superuser can use admin panel to assign correct groups to the user. Please use the command below:

docker exec -it cvat bash -ic '/usr/bin/python3 ~/manage.py createsuperuser'

Type your login/password for the superuser on the login page and press Login button. Now you should be able to create a new annotation task. Please read documentation for more details.

The command below will stop and remove containers, networks, volumes, and images created by up.

docker-compose down

If you want to access you instance of CVAT outside of your localhost you should specify ALLOWED_HOSTS environment variable. The best way to do that is to create docker-compose.override.yml and put all your extra settings here.

version: "2.3"

services:
  cvat:
    environment:
      ALLOWED_HOSTS: .example.com
    ports:
      - "80:8080"

It is possible to proxy annotation logs from client to ELK. To do that run the following command below:

docker-compose -f docker-compose.yml -f components/analytics/docker-compose.analytics.yml up -d --build

You can use a share storage for data uploading during you are creating a task. To do that you can mount it to CVAT docker container. Example of docker-compose.override.yml for this purpose:

version: "2.3"

services:
  cvat:
    environment:
      CVAT_SHARE_URL: "Mounted from /mnt/share host directory"
    volumes:
      - cvat_share:/home/django/share:ro

volumes:
  cvat_share:
    driver_opts:
      type: none
      device: /mnt/share
      o: bind

You can change the share device path to your actual share. For user convenience we have defined the enviroment variable $CVAT_SHARE_URL. This variable contains a text (url for example) which will be being shown in the client-share browser.

CVAT usage related questions or unclear concepts can be posted in our Gitter chat for quick replies from contributors and other users.

However, if you have a feature request or a bug report that can reproduced, feel free to open an issue (with steps to reproduce the bug if it's a bug report).

If you are not sure or just want to browse other users common questions, Gitter chat is the way to go.
