Conclusion Although there are many running systems for recognition of various plates such as Singaporean Korean and some European license plates the proposed effort is the first of its kind for Saudi Arabian license plates. The license plate recognition involves image acquisition license plate extraction segmentation and recognition phases. Besides the use of the Arabic language Saudi Arabian license plates have several unique features that are taken care of in the segmentation and recognition phases. The system has been tested over a large number of car images and has been proven to be 95 accurate. References 1 Kim K. K. Kim K. I. Kim J. B. and Kim H. J.
