License plate recognition for security places

Abstract EN

The vehicle license plate recognition system is consider as the best aspects of applying computer techniques in the intelligent systems field.The goal of this research is suggest a new suitable and simply algorithm to do this work.

This algorithm concentrate on the following steps: Pre-processing the Iraqi vehicle image, cutting the registration plate image from the origin one, detection about the exact region of plate from the produced image (which is considered as the important step in the automatic recognition system), separation and cutting the words that existent in the registration plate, at last recognition the whole number by separating to its digits (which allocated in the right side of plate) by suggestion subroutine for every digit according to its attributes and Recognition the state name by the same way.

The application of this program to many of vehicles captured images (25 images) with digital camera on the fixed distance, the result are succeed with the rate 80% even with the images having some abnormalities such as dust on the plate.

The fail rate is approximately 20% .
