Working with OCR to recognize photos

Navigation
6

I am currently working on my Course Completion Work and the subject involves OCR. I did some research and found the Tesseract , I also found libraries in Nuget for it (I'm using C #). The problem is that my work is about reading Car Plate, when I pass an image of a car (of the ones that the radars take), the tesseract can not read the image, says that the image is invalid. I tried with several different images, with images that only had the plate and always the same (understand thing as error) . But if I create an image in Paint with a text and try to read, it works, but that's not what I want .

I would like to know if anyone has had experience with this and knows how to solve it, or if you know another way to work with OCR and that meets this need.

If you know another way to do in another language , please tell me, I can develop in a language other than C #.

The complete solution can be seen in this video . For what I need it is necessary to use EmguCV, OpenCV and tesseract. So I can read the vehicle plates.

There is a guy named OpenCV who solves his problems, he can capture not only Image and video, but also I have to study it that has C, C ++, Java and Python implementation. p>

I'm seriously thinking about buying this book myself, so I have a lot of interest and needs on the subject.

I had the same problem a few days ago. After testing some of what worked best for my case was ocrad , which is in javascript. I needed to recognize the title of the image from a photo taken from a document.

How good it gives you the recognition score. In my case when he gave a score higher than 60%, he considered it as recognized. But for me it only worked well after editing the image, cutting only the part that he needed to recognize.

In your case it would be interesting to evaluate only the part of the characters of the board, I think it would have better results.
