im working on ALPR and i have extracted a licens plate than i do:
  1. i remove some of small and big object
  2. extract conected components
  3. template matching for each extracted componet
it work quite good, but there is always somthing that is not a character. So i there any way to decide if extracted region is a character or not? or maybe i shoud do some more pre procesing the image?
