This program takes snapshot of car license number plate and then recognize the text on it. It is 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.

This guide shows you all the information needed for using the function. Follow the instructions and descriptions written below and you will be able to implement the license plate recognition successfully.

For the implemention use the help of your C camera application. Figure 1 - Detected license plate. Important: you should study this article in order to find out how to setup your Windows Forms Application correctly. After installation you can find the example code discussed in this page with full source code in the following location on your harddisk:. To compile this example you will need Microsoft Visual Studio installed on your computer.

License plate recognition is an extremely popular function nowadays. You can benefit from it if you wish to analyze and detect license plates in a given area where a camera is placed. This function of the Ozeki Camera SDK can be an effective help for those who would like to create monitoring or surveillance systems based on license plate recognition.

There are a lot of fields where the license plate recognition function of the Ozeki Camera SDK can be used. With the help of the license plate recognition you can develop an intelligent transportation system or help the work of border control systems.

What is more, you can analyze the traffic, the parking habits or improve the security of a parking area. We can mention other situations where license plate recognition can be used: in security monitoring, vehicle surveillance, theft prevention, controlling traffic rules. What is more, with the help of this function you can draw up a complex database of traffic. This dll is responsible for the algorithms and tools which are necessary for the CV Computer Vision actions.

After an instance has been created with the help of the static ImageProcesserFactory class we can detect on frames and on video as well. In the case of frames the output image can be created by the Process method of the instance. In the case of videos we have to use the ImageProcesserHandler mediahandler.

This is a mediahandler from a VideoHandler class so it is VideoReceiver and VideoSender at the same time which means that the input can be a VideoSender for example WebCamera and the output can also be created for a VideoReceiver. No actions are executed on the input frames they are simply forwarded by default. More instance can be added which implement IImageProcesserthey will run one after the other using the image which is before them in the list.

The example uses the FrameCapture mediahandler as well which examines only every fifth frame. You can find the descripition of Frame capture here. This is a Mediahandler, which runs the IImageProcesser interface this processes the images on the incoming video.

This is an image processer interface which can detect license plates, this implements the IImageProcesser interface. Mediahandler which prepares the image which is sent by the mediahandlers from the VideoSender class for the VideoViewerWF instances. The initialization of the global variables is the task of the Init method.

Mar 21, The massive integration of information technologies, under different aspects of the modern world, has led to the treatment of vehicles as conceptual resources in information systems.

Since an autonomous information system has no meaning without any data, there is a need to reform vehicle information between reality and the information system. This can be achieved by human agents or by special intelligent equipment that will allow identification of vehicles by their registration plates in real environments. Among intelligent equipment, mention is made of the system of detection and recognition of the number plates of vehicles.

The system of vehicle number plate detection and recognition is used to detect the plates then make the recognition of the plate that is to extract the text from an image and all that thanks to the calculation modules that use location algorithms, segmentation plate and character recognition.

Step1 : Licence plate detection. In order to detect licence we will use Yolo You Only Look One deep learning object detection architecture based on convolution neural networks. Yolo v1 : Paper link. Yolo v2 : Paper link. Yolo v3 : Paper link. Yolo is a single network trained end to end to perform a regression task predicting both object bounding box and object class. This network is extremely fast, it processes images in real-time at 45 frames per second.

First, we prepared a dataset composed of images of cars that contains Tunisian licence plate, for each image, we make an xml file Changed after that to text file that contains coordinates compatible with Darknet config file input. Step2 : Licence plate segmentation. Now we have to segment our plate number. The input is the image of the plate, we will have to be able to extract the unicharacter images.

The result of this step, being used as input to the recognition phase, is of great importance. In a system of automatic reading of number plates. Segmentation is one of the most important processes for the automatic identification of license plates, because any other step is based on it. If the segmentation fails, recognition phase will not be correct. To ensure proper segmentation, preliminary processing will have to be performed. The histogram of pixel projection consists of finding the upper and lower limits, left and right of each character.

We perform a horizontal projection to find the top and bottom positions of the characters. The value of a group of histograms is the sum of the white pixels along a particular line in the horizontal direction. The average value of the histogram is then used as a threshold to determine the upper and lower limits.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have a web site that allows users to upload images of cars and I would like to put a privacy filter in place to detect registration plates on the vehicle and blur them.

The blurring is not a problem but is there a library or component open source preferred that will help with finding a licence within a photo?

As your objective is blurring for privacy protectionyou basically need a high recall detector as a first step. Here's how to go about doing this. The included code hints use OpenCV with Python. Apply a Morphological Closing operation using suitable structuring element.

I used 16x4 as structuring element. All minAreaRect s are shown in orange and the one which satisfies our criteria is in green.

You can apply other filters you deem suitable to increase recall and precision. It looks pretty accurate and it should do exactly what you need recognize the plate regions. I would like a system where I can point a video camera at some sailing boats, all of which have large, identifiable numbers on them, and have it identify the boats and send a tweet when they sail past a video camera. I have done some googling about this a couple of months ago.

There are quite a few papers about this topic, but I never found any concrete open-source implementation. There are a lot of commercial implementations though, but none of them with a price quote, so they're probably pretty expensive. Free license plate recognition I use it in a couple of my applications.Request information by Email.

Applications which offer License Plate Recognition functionalities utilise the license plate recognition capabilities and functions of a License Plate Recognition Engine. It provides an interface between the processes of the application and the core image recognition tasks of license plate recognition.

In order to work with the API - to develop applications using the functions offered by the API - software developers need proper documentation, sample codes and program tools for the API. The License Plate Recognition Software Development Kit includes everything developers need to write, build, test, and deploy license plate recognition enabled applications.

The documentation contains the exact description of the definitions, functions and variables of the API. In order to help development work reduce development time and costs the SDK should provide well structured sample programs in source code. The ready-to-compile sample program captures an image from the video source this is done by calling the functions of a separate Video Capture Module ,reads the license plate from the captured digital image and outputs the result s on the screen.
