ANPR – Automatic Number Plate Recognition

This research was last edited on 2010/07/16 which never got published 😦

There are six primary algorithms that the software requires for identifying a licence plate:

  1. Plate localisation – responsible for finding and isolating the plate on the picture.
  2. Plate orientation and sizing – compensates for the skew of the plate and adjusts the dimensions to the required size.
  3. Normalisation – adjusts the brightness and contrast of the image.
  4. Character segmentation – finds the individual characters on the plates.
  5. Optical character recognition.
  6. Syntactical/Geometrical analysis – check characters and positions against country-specific rules.
