car license plate character recognition using OCR

hi fnds........ can any one tell me how to recognize license plate characteres using OCR...i have segment chracters but confused how to start with recognition...please help me.....in MATLAB coding...........plz give ans.........

thanks in advance

It is recommend to use standard spelling in this forum - and perhaps others also. Please note, that non-native speakers will be confused by "hi fnds" and "plz give ans.....". There is a remarkable difference between kewl and cruel.

can you give me the algorithm/code that you are using for segmenting the character in LP?

Hello. So you have reached chars segmentation step, and you have n Images of characters to be recognized. 3 methods to OCR chars image: ANN, Template mach and Correlation. The easiest way and less time consuming is to use correlation method. 'corr2' matlab function. You need to compare each segmented image against template that you have previously stored in a data file. Use max() matlab built-in function to get mached result. but take care to build that template using you country license plate police chars. Ok so accept answer and vote :-)

thank you very much sir.....i will try it...

I know, that this is a boring and not helpful answer. But I cannot resist.

Are you sure, that the automatic recognition of license plates has any positive effects on the human mankind? We had some control freaks in Germany, who wanted to register each car on each highway such that it gets clear, which people are driving to which city. I do not think, that control can replace trust and that the quality of life can be increased by a powerful security system.

@Editors and Admins: I think, this personal opinion is not completely off-topic. It does not concern Matlab code, but the ethically correct usage of Matlab. If you think such discussions should not appear in this forum, I will take this into account.

Aw...

'Super cops' with super 'posts deleting power' and high reputation are here.

A simple answer would be enough.

Ethically correct usage of Matlab?

It is used in weapons development, rockets navigation, spying satellites, and so on.

You open an off-topic discussion, on our right to help Matlab students forum.

So it apply to all auditors, not only Editors and admins.

Friendly.

As neither an editor or an admin ... I would say that this is not really an answer, but more of a comment or potentially a new question. It is by no means the most egregious use of placing a comment as an answer. As an answer, question, or comment from a newbie, I might make a comment that it is off-topic, but I think you have earned the right to steer what is on topic on Answers.

To me the more interesting question, especially given the number of questions about license plate character recognition, is what makes license plate character recognition an interesting and difficult problem. Why is it different, and particularly harder, from any other character recognition problem.
