2.3. License Plate Character size
Characters in license plates must have an average height between 20 to 80 pixels, being 25 pixels a good
reference value. Less resolution may lead character confusion in some countries. In addition, camera
sensitivity affects too. For countries in which there are different character sizes on their license plates, this
fact must be kept in mind, so the small characters are included in the detection range.
