Annotation Web

Annotation Web is a web-based annnotation system made primarily for easy annotation of image sequences such as ultrasound and camera recordings. It uses mainly django/python for the backend and javascript/jQuery and HTML canvas for the interactive annotation frontend.

Annotation Web is developed by SINTEF Medical Technology and Norwegian University of Science and Technology (NTNU), and is released under a permissive MIT license.

You are more than welcome to contribute to this project, and feel free to ask questions.

  • Fast and interactive annotation of temporal data/video using javascript and HTML 5 canvas.
  • Secure login with two-factor authentication.
  • Multiple annotation tasks are implemented, such image classification, segmentation using splines, landmark and bounding box.
