In a classification task for scene elements, how should a bicycle be labeled?

• A. Ground
• B. Hazard
• C. Unknown
• D. Object

Answer: (D)

In scene element classification, discrete items in the scene are labeled as objects rather than ground, hazard, or unknown. A bicycle is a distinct, identifiable thing with a defined shape that occupies space in the scene, so it belongs to the Object category. It isn’t the ground or surface the bicycle stands on, and while it could become a hazard in context, the standard labeling approach assigns the bicycle itself to the object category rather than to hazard. It also isn’t unknown, since it can be recognized. So the bicycle should be labeled as Object.
