Image (Old) Label Mode

Anytime you choose a piece of raw data to annotate by clicking Edit Label from the Label List page, the Label Mode will automatically appear as a separate tab, just like the one below:

Toolbar

The Toolbar is located at the far left of the screen. Here are some of the tools you can access.
  • Select Click on a single annotation, or click on anywhere on the image, hold, and then drag the mouse over the image to simultaneously select multiple annotations.
  • Move Click anywhere and hold to move the image in any desired direction.
  • Delete Once this functionality is selected, click on any unwanted annotation to delete from the image. You may also use the Select functionality to choose an annotation and then press Delete on your keyboard.
  • Draw Bounding Box After selecting this annotation click, hold, and drag your box annotation over your object class.
  • Draw Polygon Create a set of points around the outline of the class you are attempting to annotate. After connecting all the points by coming back full circle to the first point, the annotation will complete itself.
  • Draw Polyline To mark straight lines, single-click the starting point, drag the cursor to the desired end-point in the image, repeat until you double-clicking to complete the polyline annotation.
  • Draw Keypoints Use our keypoint feature to mark the human face or body pose as an object class in raw image data by first activating this annotation and then dragging this over the intended class. A keypoints template of the human body or human face figure will appear (depending on your initially chosen project settings). Once in this mode, you can manually adjust any necessary point in the annotation to fit the pose (or facial outline if you selected facial keypoint) of the object class in the image.

Top Bar

There are a few buttons near the top of the Label Mode.
  • Move to the previous/next label Click to move to the previous/next label on the list of labels you are assigned to.
  • Timer This timer helps users keep track of their time spent on each image.
  • Issues Any user can click here to open a thread. The smaller version of the same image will pop up, allowing you to leave comments on whatever portion of the image that needs a second look. Annotators can also view earlier feedback left by other project managers. Find out more about this on a related user manual: Create a New Issue Thread.
  • Shortcuts To accelerate your annotation project, look here to get acquainted with or verify keyboard shortcuts.
  • Open Label List Check here to view already-assigned labels, or if you are already finished with all labels you may click Assign me a new label to self-assign yourself more labels.

Cabinet

The Cabinet refers to the panel on the right-hand side of the Label Mode.
  • Default Class If there is more than one class (e.g. bulldozer, excavator) under one annotation type (e.g. polygon) you may choose a default class so that as soon as you finish creating an annotation object the set class will be automatically selected.
  • Property Annotation property is meant to be used to add more detailed information regarding an annotation. For example, when you label a person with a bounding box, you may also want to add additional details such the age, gender, etc. This kind of object properties can be set up when you create the project. During the project setup, you have the option to add multiple choice, multiple selection, or free response properties for each object class.
