Annotations
Below are examples of our different annotations within the dataset. Every pedestrian, cyclist and motorcyclist (higher than 50px) in every frame is annotated with a bounding box, along side with three attributes: occlusion, difficult (low contrast or unusual posture) and pose. People on posters, sculptures and groups where individuals are hard to seperate are marked as “ignore”.
