LICENSE PLATE RECOGNITION METHOD USING DIFFERENTIAL IMAGE AND NEURAL NETWORK

摘要

A license plate recognition method using a differential image and a nerve network is provided to divide the kind of a license plate of labeling and recognize the license plate with different reference fonts according to the divided license plate, thereby improving the speed and accuracy of the number recognition. A license plate recognition method comprises the following steps of: inputting a license plate image(211); analyzing the license plate image and dividing the license plate image by region(213); and recognizing the divided license plate image by applying differential image technique and nerve network technique to the divided image regions(230). A dividing method by region comprises the following steps of: dividing into an upper letter region and a lower letter region; labeling characters and numerals by each region; and dividing the license plate by type through the labeling.
