What is an annotation class in V7?
In order to better describe annotations and to differentiate them between each other, each annotation has a class, represented by AnnotationClass. An AnnotationClass is represented by two main characteristics:
- name: this is the name the human picked, for example,
car - type: this is the type of the annotation, for example,
bounding_box.
For example, in the below image, we have 2 annotations:
- an annotation with name "sun" that has the type of
bounding_box - an annotation with name "car" that has the type of
bounding_box
You can have multiple annotations of various types and names in the same DatasetItem (which is an image in this case), and classes can help you differentiate what types of objects you are marking.
