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.
