I was looking around for an OCR library - optimally it would be open-source - that I could use on some Arabic pdfs. Googling it didn't result in anything useful. I was wondering if anyone knows a related OCR library or even one that works on related languages (Farsi and Urdu could be relevant) that Arabic support could be added to.
Any general suggestions on how to approach this will be appreciated.
Starting with Version 3.01 of Tessaract-ocr it now supports Arabic
I know nothing about Arabic OCR quality, but some intelligent Googling found Sakhr's Automatic Reader. It's commercial software.
Sorry. It's commercial, and quite expensive. Arabic is probably one of the hardest languages in the world to do OCR on -- I guess it takes a lot to motivate someone to do it.
The Arabic language is sophisticated when it comes to OCR because of the nature of the language and there is no free or commercial software that can get 100% accuracy.
This is from my personal experience but you can try IRISREadIRIS pro 14.

As an old C/C++, C#, Java, JS, PHP programer, I just couldn't get used to Objective-C. The reasons are obvious. I want to continue developing iOS applications and continue using Xcode storyboards. But I seriously need an alternative to Objective-C, is there any powerful tool or framework alternatives that could help me get away from Objective-C?
By powerful alternative, I mean useful enough to use most of the device methods/functions easily and has a lot of online resources, tutorials, examples on it.
I would very, very strongly recommend that you get a good Objective-C book, or work through the Stanford iOS development course on iTunes U. Without Objective-C, you will get a lot less help with other languages, you won't be able to understand code samples, you won't understand the iOS documentation.
Try http://xamarin.com/ios - this allows you to write in C#. Personally I've used all those languages as well (other than C#) but actually prefer Objective-C.

I want to make an offline iPhone application that can grab text from a picture. Can anyone suggest the best library which I can use. I heard ZBAR and ZXING can be used only for barcode reading. Is there any other OCR Libraries for iOS to read text from images. I expect your valuable suggestions as soon as possible.
Thanks in Advance..!
Currenlty offline OCR is possible only with Tesseract
You can get source code here
Here is the good tutorial about how to use Tesseract
Also you can perform OCR on multiple language. You can dowlnoad other language trained data here
You might want to look here. They offer a large variation of language they can detect and i heard only the best from their framework.
You can also test the framework live: live demo
Unfortunately i think it is very expensive to use this framework. But if you want an A1(all my Breaking Bad fans ;-)) framework this might be your best shot.

I want to make an iphone app that has a fluid ui, great icons, fluid animations etc. and i have been trying to work on learning objective c all this past summer off of the web and I am nowhere close to being able to understand/build something like that. Sure, I understand all the programming concepts of objective c, I just dont know the how to put those in practice in a way that would produce the desired results that I described. What are some free ways to learning how to do such things as that and how long would it take? Thanks in advance.
You could try TheNewBoston's tutorials. They cover not only learning the Objective C syntax, but get into OOP concepts, software design, and developing apps for iOS. Check him out at http://thenewboston.org/. If you would like to build apps visually, try http://www.appmakr.com/ for basic apps and http://www.appypie.com/iphone-apps-builder for more advanced ones.
Hope this helps!

I'm seeking a library, technique or advice on how to read an EAN-13 barcode from an image (including ISBN,and ISSN encodings).
The image would come from a mobile phone or webcam, so resolution may be quite poor and not well aligned.
I'm specifically interested in something that could be used from ruby on rails, but answers for other languages are welcome. Open Source solutions preferred.
Leading solutions to date:
ZBar (previously known as Zebra - h/t #bgbg, #Natim) - implemented in C with interfaces for Python, Perl, and C++
ZXing (h/t #codr) - implemented in Java (J2SE and Android) with other modules/ports in varying states of development (JavaME, C#, C++, JRuby, RIM, iPhone/Objective C)
The zebra barcode reader (http://zebra.sourceforge.net/) is a small, layered bar code scanning and decoding library implemented in C (C++ wrappers are also provided). It supports many popular symbologies (types of barcodes), including EAN-13. However, I'm not aware about any Ruby bindings. The library is available under the GPL
This project might be what you're looking for: ZXing
You might want to try this if it's to allow your site's visitors to scan stuff, I think it's embeddable in your own site, but I've never used it : http://en.barcodepedia.com/
We use the Softek library.
Very pleased with the results.

I am looking for good tutorials that go through every step of creating an AR application. It would be beneficial if it also covers some of the theory behind optics and such.
A good setup is to use ARToolKit plus osgART.
The tutorial of ARToolKit also explains also some of the principles of Computer Vision:
http://www.hitl.washington.edu/artoolkit/documentation/
osgART is the ARToolKit for OpenSceneGraph and abstracts some of the principles of using a computer vision based tracking in a scenegraph application
Both toolkits have a large and vibrant development community.
MXRToolkit have good documentation and is suitable for beginner. There are some other toolkits too.
http://mxrtoolkit.sourceforge.net/
Not a trivial learning curve but OpenScenegraph is probably the main FOSS app for large applications like flight simulators.
I haven't used it but it might be worth looking at: http://developer.qualcomm.com/ar
