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: 车牌识别系统一般包括车牌定位、车牌切分、字符识别三部分,而车牌定位是车牌识别系统的基础和前提,其准确与否直接影响着车牌识别的准确率。本文针对这一关键问题进行了研究,提取了车牌的颜色特征并结合其纹理特征、几何特征以及投影特征进行准确定位。采用HSV颜色模型,利用颜色空间距离相似度计算分割颜色;针对颜色分割后的图像,车牌区域内水平方向上具有的连续跳变的特征,采用行扫描法确定车牌的上下边界;车牌区域内垂直方向具有投影特征,采用垂直投影法确定车牌的左右边界;最后根据车牌的宽高比判断是否是真实的车牌域。实验结果表明该方法效果较好、精度较高。-License plate recognition system generally includes license plate location, license plate segmentation and character recognition. And vehicle license plate location is a key stage of license plate recognition system, whose accuracy directly affects license plate recognition system’s performance. This paper studied the key issue, which mainly used color feature combining the texture feature, geometric feature to obtain accurately positioning. The HSV color space and similarity calculation was used to segmented image. Because the vehicle license plate have this property of consecutive beeps in horizontal direction, and line scanning method was used to determine the top and the bottom boundary of vehicle license plate. And also the vertical projection was used to determine the left and right boundary of the vehicle license plate because of its projection property in vertical direction. Finally, according to the HVR to judge whether the area is true. Experimental results showed that the al Platform: |
