Changing the gallery settings

The gallery view can be customized using the different controls available directly above the thumbnails. Settings you can adjust include:

  • Sort by: If you have uploaded several different rankings along with your predictions, you can select which of these to sort by in the β€œSort by”-dropdown.
  • Sort order: Select if items should be sorted in ascending or descending order.
  • Thumbnail size: AdjustΒ by selecting the β€œshow as”-dropdown and then setting the number of columns.
  • Hide labels: This adjustment hides all thumbnail-labels.
  • Display property (object detection datasets only):
  • Color settings (segmentation datasets only): Select what areas to highlight (annotation, prediction or areas where they disagree). Also contains a color legend and advanced settings for how to color areas of disagreement.
  • Chart property (sequence datasets only): Select which property should be displayed in the chart for each gallery item.

Viewing an item in the task-view

If you want to be able to view an item in more detail you can open it in the task-view. This is done by clicking the icon in the top right of a thumbnail.

When you open the item in the task view it will open in a view link. This means that any changes that you make to the annotation won’t be saved and that you can’t submit it. You still have access to all the task view's regular functions (such as edit, view etc).

For segmentation datasets, there is currently no support for displaying predictions in the task view.

Selecting items

Item can be selected individually, or as a batch.

  • Selecting individual items: When no selection is active, this is done by clicking the checkbox in the top-left corner of a thumbnail. Whenever at least one item is selected, you can click anywhere on a thumbnail to select or de-select it.
  • Batch selecting items: In order to select multiple items, use the batch selection control located above the gallery, to the left. Clicking the checkbox selects all images You can choose to:
    • Select all items
    • Select all items on this page
    • Select all items up to and including this page
