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

Description: 本程序采用一种基于垂直Sobel算子检测边缘和投影法的车牌定位方法,根据车牌区域竖直纹理突出的特点，利用Sobel垂直算子提取边缘，然后投影得到车牌的水平投影图，利用水平投影图分割出车牌，再运用膨胀运算进行车牌垂直定位。利用旋转投影法寻找车牌倾斜角度，然后用双线性插值进行车牌图像倾斜矫正。对经过精定位的车牌利用垂直投影法，找出各个字符的中心点，根据字符中心点位置进行切割。同时将切割出来的图片与数据库中的每张模板图片进行减法运算，计算该图片与模板的均方误差，其均方误差最小的模板即为识别出的字符。-This program uses edge detection and projection of license plate positioning method based on vertical Sobel operator, according to a prominent feature of the license plate area vertical texture operator Sobel vertical edge extraction, then the horizontal projection of the projector to get the license plate, the horizontal projection the Figure split out the license plate, and then use the the dilation operation license plate vertical positioning. Take advantage of the rotation projection method to find the license plate tilt angle, and then the license plate image tilt correction bilinear interpolation. The focal point for fine positioning license plate using the vertical projection method to identify each character, according to the the character center point cut. Cutting out pictures with each template images in the database, subtraction, calculation of the mean square error of the picture with the template, the mean square error of the smallest template is identified characters.

Description: 本源码是基于MATLAB实现车牌识别并语音播报。
本系统针对家庭小型车蓝底白字车牌进行识别。根据彩色图像的RGB比例定位出近似蓝色的候选区域。但是由于RGB三原色空间中两点间的欧氏距离与颜色距离不成线性比例，在设定蓝色区域的定位范围时不能很好的控制。因此造成的定位出错是最主要的。这样在图片中出现较多的蓝色背景情况下识别率会下降，不能有效提取车牌区域。对此本文提出了自适应调节方案。对分割出来的区域进行识别调整。根据长宽比，蓝白色比对候选区域进行多次定位。最终找到车牌区域。
对字符正确识别之后，用事先对对每一个字符的录音根据对应字符顺序播放。在对车牌区域识别出错、字体分割出错时程序暂停，并有语音提醒。-The source is based on MATLAB license plate recognition and voice broadcast. The system for the small family car blue and white license plate recognition. Approximate positioning of the blue color candidate area based on the ratio of RGB images. However, due to the RGB color space, the Euclidean distance between two points is not a linear scale and color distance, in the blue region of the positioning range setting is not well controlled. Therefore, the positioning error is the main cause. This appears in the picture under a blue background more recognition rate will drop, can not effectively extract the license plate area. This paper presents an adaptive adjustment program. On the segmented regions to identify adjustments. According to the aspect ratio, blue and white area than the candidate repeatedly positioning. Finally found the license plate area. After correctly identify the characters, prior to use for recording each character according to the corresponding sequence of characte Platform: |

Description: It is a vehicle s number/license plate recognition algorithm based on the very elementary technique of Templates matching. The algorithm takes an input image of the number plate (number plate should be dominant in the image) and after filtering the image, it performs region based operations. Then it tries to capture the characters regions in a processed binary image and with the aid of template matching outputs the string of number plate characters.
It s a very basic approach to the problem but still produces the appropriate results. Must check out READ_ME.txt file before going to the command prompt. Platform: |
