The module described in this chapter is aimed for marking various objects on DICOM images manually with the help of contours and exporting them in JSON format. The results of image annotation may be used for training neural networks created for recognition of image components.

The following terms will be used in the description of the image annotation module:
Object — A selected part of an image.
Annotation — Marking objects.
Class (of objects) — Objects united by a quality specified by the user. A class is characterized by a unique name and properties.
