Description: 图像分割是图像处理最基本和最重要的技术，是任何理解系统和自动识别系统
必不可少的一个重要环节.车牌以及车牌字符的提取是图像分割技术的一个特殊应
用场合，它包括车牌的定位和车牌字符的切分两个步骤。本章将对这两个步骤的算
法进行阐述.第一、二节中将分别详细介绍车牌区域的定位、切分技术 由于二值
化算法在字符的提取中具有重要的作用，因此在第三节中将作重点讨论.
-Image processing image segmentation is the most fundamental and important technology, is any understanding of systems and automatic identification system essential for an important part. License plate and license plate character extraction image segmentation technique is a special application, which includes car license plate location and character segmentation in two steps. These two steps in this chapter will elaborate algorithm. First, the two plates will introduce a detailed regional positioning, segmentation techniques as a result of binarization algorithm in the extraction of characters play an important role, so in Section III will be focused on.

Description: 本文提出了一种新的车辆许可证盘子识别,并在此基础上提出了一种自适应图像分割方法-In this paper, a new algorithm for vehicle license
plate identification is proposed, on the basis of a novel adaptive
image segmentation technique (Sliding Windows) in
conjunction with a character recognition Neural Network. The
algorithm was tested with 2820 natural scene gray level vehicle
images of different backgrounds and ambient illumination.
The camera focused on the plate, while the angle of view and
the distance from the vehicle varied according to the
experimental setup. The license plates properly segmented
were 2719 over 2820 input images (96.4 ). The Optical
Character Recognition (OCR) system is a two layer
Probabilistic Neural Network with topology 108-180-36, whose
performance reached 97.4 . The PNN was trained to identify
multi-font alphanumeric characters from car license plates
based on data obtained from algorithmic image processing. Platform: |

Description: Automatic Vehicle Identification (AVI) has many
applications in traffic systems (highway electronic toll collection, red
light violation enforcement, border and customs checkpoints, etc.).
License Plate Recognition is an effective form of AVI systems. In
this study, a smart and simple algorithm is presented for vehicle’s
license plate recognition system. The proposed algorithm consists of
three major parts: Extraction of plate region, segmentation of
characters and recognition of plate characters. For extracting the
plate region, edge detection algorithms and smearing algorithms are
used. In segmentation part, smearing algorithms, filtering and some
morphological algorithms are used. And finally statistical based
template matching is used for recognition of plate characters. The
performance of the proposed algorithm has been tested on real
images. Based on the experimental results, we noted that our
algorithm shows superior performance in car license plate
