MTurk Worker Annotations

Workers first denote if the focus of the image is on the main object (core), or a separate or background object (spurious). They also mark their confidence on a scale of 1 to 5, and provide written explanations for their annotation.

Separate Object	5	The focus was on the hand's of the potter. there is a pottery wheel in every photo, but that is not the focus.
Separate Object	5	The red areas focus on the potter's wheel, while the focus of the images is usually the pot or potter.

Separate Object	5	The focus of the red region in the highlighted visual attributes is on the hand not part of the potter's wheel.
