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.



Main Focus	Confidence	Explanation
Main Object	5	The focus is primarily on the beetle. however, there is some overlap with the plant on one image.
Main Object	5	Focus is directly on the ladybug, instead of around the leaf
Separate Object	4	Leaves are not a part of the ladybug
Main Object	5	All five image have focus on main object;s ( ladybug.) part.
Background	3	The focus is on leaf which is in the background of ladybird


Votes for core: 3, Votes for spurious: 2. Feature is thus annotated as core for the class.
