Data view types

The central display area shows the images in an icon view format by default, but you can select lists, and cards views as well. Key features:

Icons view

The Icons View in the Assignment Browser displays your assignment items in a thumbnail grid layout, providing a quick visual overview of your data.

• Displays a thumbnail preview of images.
• Supports multiple media types including images of animals, landscapes, and various subjects.
• Allows selection of items for annotation or QA review.

Lists view

The list view displays assignment items in a structured table format view. Each row represents a file/item with associated metadata.

• Name: The filename of the image (e.g., 49910fd3ff.jpg).
• Created At: Timestamp indicating when the file was added (e.g., November 18th, 2024, 12:21:49 pm).

Cards view

The Cards View in the Assignment Browser presents assignment items in an organized card-style layout, designed specifically to streamline bulk classification workflows.

The main purpose of the Cards View is to enable fast and efficient bulk classification, allowing annotators to process multiple items without switching between views or opening the Annotation Studio.

Annotation status by color

In the Assignment browser List View, the color coding of items indicates their annotation task status:

🟢 Green color - completed tasks

Items with a green background (e.g., 7a4c8ba397.jpg in the screenshot) indicate that the annotation task has been completed. This means that the file has gone through the annotation process, and no further action is needed.

⚪ No Color / Default Background (Not Completed)

Items with no color / default background mean that the annotation task is not yet completed. The file is still pending for annotation, review, or further processing.

🔴 Red color - discarded tasks

Items with a red color to indicate that are discarded. This could mean incorrect annotations, missing required data, etc.
