Overview

Main Sections of an Image Annotation Studio
- Section 1: Label Picker and Annotation Tools (left-side panel)
- Section 2: Annotation Lists, Attributes, Modalities, and Item Details (right-side panel)
- Section 3: Image Canvas
- Section 4: Item Info & Controls (top-side panel)
- Section 5: Item's View Controls (bottom-side panel)
Image Canvas
It serves as the primary workspace for annotating images, offering a variety of annotation tools for the annotation process.

Work in the Image Annotation Studio
How to Create Image Annotations?
- 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.
In Dataloop's Image Annotation Studio, images are automatically rotated based on the Exif metadata. This ensures that all images are correctly oriented when you work with them during the annotation process. For more information, see the EXIF Orientation Value article.
A new annotation is created, and the new annotation is listed both on the annotation list and the transcription list.
For more actions available on the Image Studio, see the Annotation Studio Basics article.
