Take human as 0.5 m (width) × 1.8 m (height), and limit length is
0.75 m. The vehicle limit length is 2.3 m.
 Detect target: The target should be at least 1.5 pixels on the
image.
 Recognize target: The target should be at least 6 pixels on
the image.
 Identify target: The target should be at least 12 pixels on
the image.
