Annotating Your Assigned Tasks¶

If an unfinished task is assigned to you directly, you can click the Annotate button next to the task on the Tasks table to begin annotating randomly presented images. The annotation screen allows you to click-drag to create a bounding box. Use the down arrow key or begin typing to select the correct label for the annotation. In addition to the click-drag motion for creating annotations, the following tools are available to you in the annotation interface:

• 
• 
• scroll bars to pan across the image to look for parts to annotate
• 
• Done to finish the ground truth stage of this image, making it as completely and accurately done. If any annotations were created, modified, or destroyed, they are now saved as ground truth. If no annotations were present when Done was clicked, the image is considered empty.

reaches 100%), a page noting the successful completion of annotation for the task appears. Click the Tasks button on the menu to return to the Tasks view and start your next assigned task.

Annotation Toggle¶

When annotating or ground truthing a task, annotation labels can be applied to specific regions or objects in an image as tags or markers.

Toggle the visibility of the annotation labels and label delete buttons by clicking the Show Labels checkbox in the bottom left corner:

• Toggle the checkbox on to view the annotation labels and trash can icons to delete annotation labels. This is the default state.
• Toggle the checkbox off to hide the annotation labels and delete buttons, so the image and annotations are fully visible.
