Note:

Detection Distance: Detects objects, but cannot recognize their characteristics

(objects must cover more than 3.6 pixels of the image).

Recognition Distance: Classifies objects into general categories, such as human,

vehicle (the object must cover more than 14 pixels of the image).

Identification Distance: Classifies objects into specific categories based on their

characteristics, such as engineering truck, car (the object must cover more than 28

pixels of the image).
