Point

Updated 2 weeks ago by Alex Cota

Overview

The point tool is used to annotate a single x, y coordinate in an image.

Configuring the Point tool

Setup steps
  1. Create a project.
  2. Select "Image editor" as your label editor.
  3. Click "Add Object" and name your object.
  4. Select "Point" as your labeling tool.
  5. [OPTIONAL] Configure nested classifications.
  6. Click "Confirm".
  7. Click "Complete setup".

Nested classifications

Any existing classification tools can be nested within the tool to capture metadata about the label. The example below demonstrates how to nest a single-choice radio question within a point object.

Creating Instances

From the labeling interface, you can use the same class for more than one annotation. For example, if there are 2 eyes in an image and you would like to assign the "Eye" class to both, you can create multiple instances of the "Eye" class.

Follow these steps to create multiple instances of the same object:

  1. Select a class and draw the object.
  2. Select the same class again.
  3. Draw the next instance of the object.

Label format

Point labels can be imported as an existing label or a model prediction. They can also be exported in JSON format.
