Abstract :
License plate location is one of the key link in the license plate recognition process. Whether the plate location is successful and how accurate is the location decide directly the recognition and the effects in the latter part. For the license plate area has a high density difference in the difference image,we have put forward an algorithm for the license plate location based on the density and projection. The results show that this method can quickly and correctly locate the license plate area.
