Note:
①Detection Distance: Detects objects, but cannot recognize their
characteristics. Detected objects only cover a small amount of pixels (objects
must cover more than 3.6 pixels of the image).
②Recognition Distance: Classifies objects into general categories, such as
human, vehicle, and building (the object must cover more than 14 pixels of the
image).
③Identification Distance: Classifies objects into specific categories based on
their characteristics, such as soldier, pickup truck, and gas station (the object
must cover more than 28 pixels of the image).
