I want to develop an application in which I capture an image of text (a business card, for example), and now I want it to be scanned and converted into an editable text. Is it possible? Something like optical character recognition.
Here are some examples
OpenCV library for Apple iOS. It includes two XCode projects: one for iPhone, the other one for iPad Try OpenCV with iOS
demo application that utilizes the Tesseract library as a static library compiled under Mac OS 10.6 Try Tesseract with iOS
And Here is good question realte to this.
Hope this information should be useful for you.
Thanks

i want to use Tesseract for my iphone app for OCR, but its not recognise the low resolution image text, so whats the limitation of Tesseract OCR for iPhone SDK
Please refer Real TIme Image Processing (OCR)
Abbyy cloud is an cloud service for doing OCR online.
Tesseract works great on iOS. The hardest part is installation.
Here is a sample project that uses it on github:
https://github.com/AdamGluck/split
(Disclosure, this is a project I worked on for fun. However, it implements tesseract for iOS.)
We used this framework:
https://github.com/ldiqual/tesseract-ios
I'll note that we got better results when we made the image a sharper black and white (in the project). Although this was not that necessary to get good results.
I am starting a project with PhoneGap and it will work on iPhone and Android devices. The question is how to implement support for different screen sizes and resolutions.
For example, I have an icon inside the application: small waves to run some action. What size of this icon should be to be shown well in all possible devices (iPhones/Androids). Should I include several versions of the same image?
The same question about text. How can I be sure the text will be readable and will stay in line on different devices?
thank you
If you are a MAC user you could give the new dreamweaver 5.5 a shot. It will structure your app and even build a debug version for testing. You can do this with either the ANDROID SDK or the iOS sdk. Of course, it will work on a PC as well but there is not support for the iOS sdk.
Using the Adobe Dreamweaver 5.5 it has specific mobile framework to recognize jqm or jqtouch and inserts phonegap.js on build into the packaged product. It also allows you to scale the testing screen for the different sizes of mobile devices. From android, iphone, to ipad(and more)
Here is an example: Dreamweaver with phonegap support
We're creating an iOS app that basically scans badges at events and collects contact info. We're looking for an iOS library that can read not only the number of the barcode, but also any additional information that's included (contact info). Does anyone have any library suggestions or will this have to be a custom library? Thanks in advance!
Updated:
Use AVCaptureMetaDataOutput in AVFoundation which works with minimum deployment target iOS 7.
Previous Answer:
Have been using ZBar SDK in most of our projects. Picks up barcode and scans very fast, easy to customize focus area from SDK. Tested on iPhone 3GS, iPhone4/4S, iPhone 5 and iPad

iOS7 has built in functionality scanning BarCodes not sepearate sdk is required; if your deployment target is iOS7
Is your barcode format up to you, or do you have a predetermined symbology you have to work with?
There is this: http://shopsavvy.mobi/sdk/. Don't know why that wouldn't work for you, unless you object to the licensing terms.
Checkout ZXing ("Zebra Crossing") at http://code.google.com/p/zxing/
Reads almost every kind of barcodes and we used it with great success previously.
Use ZBAR its the best, we used it in our app www.infomq.com and its is really stable and scans reliably.
Basically you want to use PDF417 which is a stacked linear barcode symbol. Check out the pdf417 decode on Sourceforge.
Is it possible on an iPhone app to take a picture and extract an string from the picture? We'd like to make our app to look for a serial number on a database (very long number) without the user having to type it.
Is there any Cocoa/Objective-C API for this or any C/C++ library that can be used in an iPhone app?
Thanks in advance!
You can have a look at the tesseract-ocr project. It's not actually made to use on an iPhone but I believe others have made great use of it on the iPhone.
Here is a demo that makes use of the tesseract ocr engine.
I was looking for something similar and came across ABBYY's mobileOCR solution
I've not used it yet and have no idea how much it is but you should be able to integrate it into your app by all accounts.
I have this in my bookmarks: http://code.google.com/p/zxing/
It has iPhone, Android and Java code to deal with image capture and bar codes.
I haven't test it yet.
Here's another implementation of Tesseract on the iPhone: http://robertcarlsen.net/dev/pocket-ocr
Tesseract-OCR now has iOS version:Tesseract-OCR-iOS
I want to used the particular fonts for my application. But I don't how can use that font that are in the iPhone SDK library.
Any idea how can I do this ?
By the way I want to use hindi and punjabi fonts in it.
The FontLabel open source project provides a means of drawing your own .ttf fonts on the iPhone.
There is currently no official way to do this; but given the presentations of iWork on the iPad, it's possible that the 3.2 SDK adds this.
Edit: Assuming Jasarien is right about this; you'd probably be better off developing for iPhone OS 3.2; as you'll need an iPhone Dev Central membership to publish your applications at any rate; you might as well get started right away.
