When answering a question please:. Read the question carefully. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome. Don't tell someone to read the manual. Chances are they have and don't get it.

License Plate Recognition System Source Code Matlab![]()
Point the package at an image or video stream, and it quickly scans each frame for license plates in US or European formats, reporting whatever it finds along with a confidence level. This kind of technology has all kinds of possibilities, some good (create an automated home which recognizes when individual family members arrive), some more worrying (keep a history of who’s visiting your neighbor, and when). The open source build is aimed at developers, and really just the core library with some console tools, but it’s easy to test - even if you don’t have an IP camera. All you have to do is point the bundled command-line tool at your target image or video, like this: alpr -c us samples/us-1.jpg alpr -c eu samples/eu-clip.mp4 Any likely plate characters are displayed within a few seconds. If you like the idea, but prefer something a little easier to use, OpenALPR’s website where you can upload test images.
The company also offers commercial products where your IP camera can be automatically monitored, license plates recorded, and the full history available at any time via a web dashboard ($50/ month per camera). Is an open source package available for Windows, Linux, OS X and more.
Project Description ANPR MX is a simple Automatic Plate Recognition DLL for ordinary North American type plates. (It won't identify 'European' type ones.) It uses OpenCV for image processing and is capable of analyzing images with a maximum resolution of 800x600 or lower. (.jpg /.png) file formats allowed. The code is partially based on the JavaANPR project, which is owned by Ondrej Martinsky. (See: for details.) However, the following things were modified:. Code entirely written in C# using VS 2010 and the.NET Framework 4.0.
Uses OpenCV instead of the java.awt libraries. Replaces the plate band finding algorithm with a different approach based on OpenCV Blobs. Recognizes the North American average plate size only.
It won't work for the European type plates. The library is simple and ready to be used on commercial or open source projects as it is licensed under the new BSD format. To make it easy for anyone to understand how the DLL works, I also provided an executable that shows its capabilities. You can also download a series of random car photos to test it. (See the 'Downloads' section.) IMPORTANT Please make sure you agree with the following licenses before you proceed to use this software:. BSD (for OpenCV and ANPR MX). LGPL 3 (for linking to OpenCVSharp) In case of doubts or comments, please feel free to contact me at [email protected] Donate ANPRMX is a free open source project that is developed in personal time.
If you find it useful and want to show your support, ANY amount donated is deeply appreciated. Executable example.
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? Nas stillmatic zip download.

Caveats;. I know nothing is perfect and image recognition of this type will provide false positive and negatives. I appreciate that we could ask the user to select the area to blur and we will do this as well, but the question is specifically about finding that data programmatically; so answers such as 'get a person to check every image' is not helpful. This software method is called 'Automatic Number Plate Recognition' in the UK but I cannot see any implementations of it as libraries. Any language is great although.Net is preferred. EDIT: I wrote a for this. As your objective is blurring (for privacy protection), you basically need a high detector as a first step.
Thank you for looking at my question, Had a new server installed yesterday running MS SQL Server 2008 on SBS 2011. Databases have been restored successfully - can see tables, views etc. I tried to create on ODBC connection on the server and get: Connection Failed: SQLState: '01000' SQL Server Error: 2 [Microsoft][ODBC SQL Server Driver][DBNetLib]Connectio nOpen (Connect()) Connection Failed: SQLState: '08001' SQL Server Error: 17 [Microsoft][ODBC SQL Server Driver][DBNetLib]SQL Server does not exist or access denied I don't know where to start looking - please help. Error 08001 sybase odbc driver client unable to establish a connection.

Here's how to go about doing this. The included code hints use OpenCV with Python. Convert to Grayscale. Apply Gaussian Blur.
Img = cv2.imread('input.jpg',1) imggray = cv2.cvtColor(img, cv2.COLORBGR2GRAY) imggray = cv2.GaussianBlur(imggray, (5,5), 0) Let the input image be the following. Apply Sobel Filter to detect vertical edges.
Threshold the resultant image using strict threshold or OTSU's binarization. Cv2.Sobel(image, -1, 1, 0) cv2.threshold. Apply a Morphological Closing operation using suitable structuring element. (I used 16x4 as structuring element) se = cv2.getStructuringElement(cv2.MORPHRECT,(16,4)) cv2.morphologyEx(image, cv2.MORPHCLOSE, se) Resultant Image after Step 5. Find external contours of this image. Cv2.findContours(image, cv2.RETREXTERNAL, cv2.CHAINAPPROXNONE).
For each contour, find the minAreaRect bounding it. Select rectangles based on aspect ratio, minimum and maximum area, and angle with the horizontal.
