Label Me - Annotation Tool

Annotation Tool

The LabelMe annotation tool provides a means for users to contribute to the project. The tool can be accessed anonymously or by logging in to a free account. To access the tool, users must have a compatible web browser with javascript support. When the tool is loaded, it chooses a random image from the LabelMe dataset and displays it on the screen. If the image already has object labels associated with it, they will be overlaid on top of the image in polygon format. Each distinct object label is displayed in a different color.

If the image is not completely labeled, the user can use the mouse to draw a polygon containing an object in the image. For example, in the image to the right, if a person was standing in front of the building, the user could click on a point on the border of the person, and continue clicking along the outside edge until returning to the starting point. Once the polygon is closed, a bubble pops up on the screen which allows the user to enter a label for the object. The user can choose whatever label the user thinks best describes the object. If the user disagrees with the previous labeling of the image, the user can click on the outline polygon of an object and either delete the polygon completely or edit the text label to give it a new name.

As soon as changes are made to the image by the user, they are saved and openly available for anyone to download from the LabelMe dataset. In this way, the data is always changing due to contributions by the community of users who use the tool. Once the user is finished with an image, the Show me another image link can be clicked and another random image will be selected to display to the user.
