Overview

Dataloop offers an image studio that is designed for annotating or labeling images. Annotation in this context involves adding metadata or labels to specific elements within an image, such as objects, regions, or features.


Main Sections of an Image Annotation Studio


Image Canvas

It serves as the primary workspace for annotating images, offering a variety of annotation tools for the annotation process.


Before You Begin

Supported Image formats

Refer to the Supported Image formats section to view the supported image formats in the Image Studio.


Task Prerequisites

Labeling work is performed in the context of a labeling task. Create your task with the intended data (image files), the Recipe (labels, attributes, and labeling instructions), and annotate team members.


Supported Annotation Tools

Refer to the Annotation Tools section to view the supported annotation tools formats in the Image Studio.


Supported Image Annotation Types


Annotation ID

Annotation IDs are used to differentiate instances of annotations.

For example, In the above screenshot, Bird-3#002. Here, the annotation ID is 002. There might be five annotations with the label Bird, but each requires a unique ID.

Work in the Image Annotation Studio

Create Annotations

Important

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.

  1. Open the Image Annotation Studio.
  2. Select the desired annotation tool from the tool section.
  3. 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.
