____________________________________________________________________________________________

Functionality is available in a separate module which is activated in the Pro edition for an extra fee
____________________________________________________________________________________________

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.

The image annotation module is available in the ﬂat image viewer tab and provides for the following functions:

create / edit a list of object classes and unite classes in groups;
select objects belonging to diﬀerent classes with contours;
export and import the tree of object classes and groups;
save image annotation results and open them to continue work;
export annotation results with DICOM data.
