Use the Brush tool, the Polygon tool, or Smart Segmentation to annotate your pixel projects.
Select the brush tool, adjust the brush size, and outline your object.
Select the polygon tool, and outline your objects using clicks at each corner of your shape.
In the images tab, select Smart segmentation next to the image you want to annotate. Go to the editor, click on the segment you want to annotate, press the spacebar, and assign it a class.
In the Images tab, select Smart prediction next to the image you want to annotate. Next, choose a model:
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.
Panoptic segmentation (trained on COCO): Assigns all the pixels to classes. Use this model to detect countable objects, such as cars, and uncountable objects, such as the sky.
Go to the editor, click on the segment you want to annotate, and assign it to a class.
Use the Eraser Brush tool and the Eraser Polygon tool to fix your annotations.
Select the eraser brush and brush over the areas you want to delete.
Select the eraser polygon, and remove areas using clicks at each corner.
Select the annotation you want to delete, find it in the list in the right panel, and select X.
To delete all the annotations, select Revert (trash icon) in the top panel or press Ctrl+Shift+R.
You can assign a class to your annotation in five 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: Click Class selection and choose a class, create an annotation, and press the spacebar.
Method 4: Select the Eyedropper tool, click 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 5: After applying Smart Segmentation to an image, choose a number of segments from the left panel. The higher the number you choose, the more your image will be segmented, and vice versa. Now select a segment, click the plus button in the right panel, choose a class.
Alternatively, 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.
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.
Segmentation: 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 or press Enter.
Adjust the settings of your image by dragging the slider to the left or to the right:
Fill (instance transparency)
Lines (segment 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.
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 the comment, select Delete, and confirm your action. Only Team owners, Team admins, Project admins, and QAs can delete comments. The red dot on the comment icon will disappear.
