You will be shown 12 images. The task is to outline all of the mouses that appear in the 12 images.

Example (object to label: mouse):

Note: the polygon should closely follow the outline of the object. All the objects should be annotated individually. Do not group them with a single polygon. Do not label other objects than mouses.

Example of BAD LABELING:

Note: the polygons do not follow the shape of the objects. There are many objects labeled, and not just mouses as requested.

Labeling guidelines

The following steps describe how to label an object:

  1. Start by pressing the left mouse button at some point along the boundary of the object.
  2. Continue clicking along the boundary of the object to create a polygon.
  3. Once you have finished clicking along the boundary of the object, either click on the first point or press the right mouse button to complete the polygon.
  4. A window will now appear asking for the object's name. Enter the object's name and click the "Done" button.

Some additional guidelines:

  • View the entire image. Make sure that your browser occupies the entire screen and that you scroll to see the entire image. If you label an object on the edge of your browser, make sure to scroll so that the entire object is visible.

  • Follow the object outline. Click on top of the object boundary so that the polygon accurately delineates the object outline. The ideal outline should be good enough for somebody to recognize the object just by seeing the drawn polygon.
