Automatic License Plate Recognition (ALPR) system has a significant role in safety, security and other services of transportation. ALPR is becoming a crucial part of an intelligent transportation system. Any ALPR system includes plate localization as an important step. In this paper, a simple technique to localize the license plate area has been proposed using wavelet transform and morphological operations. Most of the previous works are limited to particular environment and physical conditions, however, the proposed method of license plate localization (LPL) can be used in different environmental conditions and it is also robust to the size and color of the license plate. This method provides good accuracy (96.33%) with less processing time.
