Work in the Image Annotation Studio
Create Annotations
The annotation creation steps are different for each annotation tool. Make sure you refer to the Supported Image Annotation Types section to become familiar with the annotation steps for various types of image annotation.
- Open the Image Annotation Studio.
- Select the desired annotation tool from the tool section.
- Click and drag the mouse on top of the image. The selected place of the image changes color to match the color of the label.
A new annotation is created, and the new annotation is listed both on the annotation list and the transcription list.
