Use these tools to annotate your vector projects. Choose the tool depending on the shape of the object you want to annotate.
For details or corners, such as eyes and joints.
For thin objects, such as light poles and cables.
For irregular shaped objects, such as organs and animals.
For objects in the shape of a square or rectangle, such as buildings and boxes.
For objects in the shape of a circle or an oval, such as fruits and cells.
For objects that have depth, such as vehicles and furniture.
Alternatively, you can create templates to make accurate annotations.
To do that, go to Templates, and choose one of the four available templates: Human Pose, Hand Pose, 2D Cuboid Right, or 2D Cuboid Left.
You can also customize a template from scratch. Follow these steps to create a template:
Select New Template outside the editor, and enter a template name.
Click Open image and choose an image from your computer to use as a guide for your template. You may skip this step, but we recommend it for accurate results.
Create a template using the Point and Line tools.
Tap on the points to label them.
Select Create when you’re done.
In the Images tab, select Smart prediction next to the image you want to annotate. Next, choose a model:
Cars: Predicts vehicles.
Instance segmentation (trained on COCO): Predicts your instance’s class label, bounding box, and binary mask. Use this model to detect countable objects, such as cats.
Human pose keypoint detection (trained on COCO): Predicts human beings.
OCR (English text): Predicts texts in English.
Building detection for aerial imagery: Predicts buildings.
Object detection (trained on COCO): Predict objects using bounding boxes.
Go to the editor, click on the segment you want to annotate, and assign it to a class.
Select the annotation you want to delete, find it in the list in the right panel, and select X. Or you can select the annotation and press the backspace key or Del (Windows).
To delete all the annotations, select the Revert (trash icon) in the top panel or press Ctrl+Shift+R.
You can assign a class to your annotation in four ways:
Method 1: Right-click on your annotation and choose a class from the drop-down menu.
Method 2: Select your annotation and choose a class from the drop-down menu in the right panel.
Method 3: Select the Eyedropper tool, click on an object to sample its class. The Eyedropper tool will change into the Bucket tool. Next, select your unassigned object(s). The Eyedropper tool eases the class assignment of multiple objects.
Method 4: You can assign a class to your object before annotating it. Follow these steps:
Select the class selection tool from the left panel.
Choose a class.
Annotate your object using any tool you want.
Your object will be immediately assigned to the class you’ve chosen.
You can change your annotation’s class in two ways:
Method 1: Right-click on your object and choose a class from the drop-down menu.
Method 2: Select your object, find it in the list in the right panel, select the ellipsis button, and move your object to a different existing class.
If you have similar objects in one image, say a shelf that holds milk boxes, you might want to copy the annotations to save time. Follow these steps:
Annotate an object using any of the available tools.
Select the annotation, and click Copy in the top panel, or press Ctrl+C.
Click Paste in the top panel or press Ctrl+V.
Place the object wherever you want.
Use the Duplicate mode to make video annotations easier. Once you upload a video, it will be split into several frames or images.
Start working on the image you want to annotate first using the available tools. Instead of copying the annotations from one image to another one by one, use the duplicate mode:
Select Duplicate mode in the top panel.
Hover over the objects you want to copy, and select the plus button.
In the image panel, click on the image you want to copy the objects to.
You can change the dimensions and the locations of your objects without disabling Duplicate mode.
If you want to continue duplicating the objects to additional frames, the modified objects will be duplicated.
Duplicate mode allows you to copy annotated objects as well as their assigned classes and attributes.
In some cases, you might need to use more than one tool to annotate a single object. To let the system know that several annotations belong together, you need to group them. To do that, follow these steps:
Select an annotation, and press and hold the Ctrl key.
While holding the Ctrl key, click on the elements you want to select.
Select Group in the top panel.
If you think you’ve made a mistake, select Ungroup or press Ctrl+Shift+G and start over.
Select the eye button in the top panel or press R to show or hide the annotated objects.
Click the filter button in the image panel to filter the images by:
Assignee: No assignee, No assignee: QA, and No assignee: Annotator.
Annotation status: Any, Not started, In progress, Quality check, and Returned.
Prediction: Any, Not started, In progress, Completed, and Failed.
Pinned images: To do that, select the pin button.
Select Reset > Apply to remove the filter.
Follow these steps to add tags to images:
Select Tags in the left panel.
Enter a tag in the text box.
Click the + button.
Adjust the settings of your image by dragging the slider to the left or to the right:
Fill (instance transparency)
To set your image as complete, select Complete at the bottom of the right panel. Learn about the project workflow here.
To send your image to the QA(s), select the down arrow at the bottom of the right panel and click Quality check. Learn about the project workflow here.
Annotators and QAs can request images by selecting the plus button in the Images panel. They will be automatically assigned up to 50 images and cannot have more than 50 images at a time. Annotators and QAs have to finish working on the assigned images to be able to request more images.
In the image panel, hover over the info (i) icon to see the image name and the names of the QAs and Annotators. You can copy and paste the image name. You can also hover over the icon on the left to see the image status.
Method 1: Select Show/Hide labels in the top panel to see the following labels on your image:
Method 2: In the right panel, select Show/Hide labels next to a class to see the labels of the instances that belong to that class.
Method 3: You can also expand an instance in the right panel (labeling) to see its attributes and point labels.
Select Comment in the left panel or press C, and click where you want to add the comment. Next, enter a text and hit send. A red dot will appear on the comment’s icon.
Select the comment and click the green arrow. Only Team owners, Team admins, and Project admins can resolve comments. The red dot on the comment icon will disappear.
Click on the comment, select Delete, and confirm your action. Only Team owners, Team admins, and Project admins can delete comments. The red dot on the comment icon will disappear.
