Abstract: The algorithm of Adaboost has already achieved a great success in system of face location, it’s simple reliable and accurate. This algorithm solves the contradiction between speed and precision in real-time object detection. On the other hand. The location of the vehicle license plate is primary step in the vehicle license plate recognition system and the accuracy of locating plays an important role in this system. So this paper presents a new algorithm to locate the license plate based on Adaboost in order to search a new efficient way of license plate location. The result of experiments proves that the algorithm is feasible.
