摘要:

自动车牌识别(ALPR)是一个具有挑战性的研究领域,由于其重要性的各种商业应用。整个问题可以细分为两个关键模块,首先,从车辆图像中定位车牌,其次,提取车牌的光学字符识别。在目前的工作中,我们集中在问题的第一部分,即,印度商用车牌照区域的本地化是为印度车辆开发完整ALPR系统的重要一步。该技术是基于基于颜色的车辆图像分割和识别潜在的车牌区域。真正的车牌定位的基础上,四个空间和水平对比度的功能。该技术成功地定位实际的车牌在73.4%的图像。

英文摘要:

Automatic License Plate Recognition (ALPR) is a challenging area of research due to its importance to variety of commercial applications. The overall problem may be subdivided into two key modules, firstly, localization of license plates from vehicle images, and secondly, optical character recognition of extracted license plates. In the current work, we have concentrated on the first part of the problem, i.e., localization of license plate regions from Indian commercial vehicles as a significant step towards development of a complete ALPR system for Indian vehicles. The technique is based on color based segmentation of vehicle images and identification of potential license plate regions. True license plates are finally localized based on four spatial and horizontal contrast features. The technique successfully localizes the actual license plates in 73.4% images.
