Optical Matching/ OCR

I am trying to find a API that would match two images I have and give a % similarity and also even match text on the two images being compared.

Thanks, I would like to use this in my .Net application. Is there any image processing library that is more suitable to use with .net and perhaps even written in .Net?

TommySzalapski

You don't want image processing written in .NET. It's too slow. What you really want is image processing code written in C with .NET wrappers around it so you can call the routines from .NET.

Fortunately for you, you are not the only one who wanted this. Emgu CV is exactly what you are looking for I think. You can write all your code in .NET, but the behind-the-scenes code for the processing will run in efficient and fast C code.

It is indeed an awesome library for image processing but I will have to develop a lot of intelligence teaching this system about a ton of languages I want my software to support. Is there perhaps some other software for just OCR that is aware of a group of languages?

Thanks

Thanks Tommy! It looks very promising.
I tried downloading it and when I launched the Demo application, it crashes. It was heart breaking :P

Hmm... Make sure all the dlls are in the right folders (Tessnet2.dll). Probably needs to be in the same folder as the .exe or a folder referenced in your %PATH% system variable.
I assume you have the needed runtimes already installed.

Yes, I tried every combination of folder structure and tried putting the files everywhere just in case I was doing wrong. The moment I click on "OCR", the button that is supposed to convert, it crashes! No events in event viewer, nothing. Just dies.

I guess the next step would be to see if you can compile a quick test project. If that works, who needs the demo? Maybe they referenced some weird runtime functions or something that your computer doesn't have.

I actually did. I took the source of the demo application and compiled it and then used the newly generated exe. But did reuse the existing .net wrapper since I did not have VC++ to recompile it on my machine.

Works fine! Had to change some folder structures!! Thats all!
