I want to build an iOS application that recognizes patterns in a cup of coffee.
For example http://en.wikipedia.org/wiki/File:Coffereading.jpg .
This image recognition script could run on the client side (iphone eventually) or on server side.
The goal of the app is to take a picture of a cup of coffee, analyse patterns,
and compare them with images/patterns that are already stored in a database, and return the most appropriate one
I have no experience in this field and after doing some research, I found some libraries that might help me do this: openCV, kooaba, snaptell, and server side libraries like afroge.net.
This confused me alot. I want to know if this is possible using libraries like the ones above, or any other one. And how much time/effort should be given if any modification should be made on one of those in order to achieve my goal
You can also read more information about reading fortune under this link: http://en.wikipedia.org/wiki/Tasseography

In short: It can be done with OpenCV. You can use it to recognize the coffee cup (circle and/or square detection). After that you have to take a look at "feature detection" (SURF ist a good way to go) to match the coffee patterns.

Yes, it can be done. But it's a huge topic and very complex.
Your best bet is to license third party code that will handle all the difficulties for you.

I have done lots of applications for iOS using Xcode. And i want to explore the feasability of Augmented Reality in iPhone. I searched for it and found that we need SDKs for it i.e Qualcom or String. Can anybody suggest me whichone is best to start with? And any sample tutorial for start-up related to that.?
If you want to learn about Augmented Realty and many different APIs, IDEs, Engines and SDKs, this book may be the best resource for you
Pro iOS 5 Augmented Reality
It is for iOS 5, but I see no adoption that prevents it from working with iOS 6. It is great! It shows Qualcomm demoes, Open-CV, String and more!'
The author works with you throughout the book with examples and explanations which are beyond interesting and cool.
After reading this book I feel like a professional, just read the reviews, a great valuable book!
Answering your ultimate question, which is the best SDK/API? I think that it depends on what you want, they have different purposes, functionalities, learning curves etc. I suggest you read this book to explore all
You could use iPhone-AR-Toolkit. It's up on GitHub, and I've added in lots of helpful things like a radar, modern callouts etc...

Can you auto take multiple pictures and then edit them in real time for an iphone app? Like say u want to make a video of a man and add a beard to him can you do it while streaming? the mustach moves according to where his face is detected and say take about 5-15 frames per second?
I guess you can.
It would involve tracking some facial features or markers added for the purpose at the least. However this is such a vast and complex field, you'll hardly get a single advice here that will get you going.
If you really mean it, I'd suggest looking for Augmented Reality libraries, there's a few out there. Most of them work by tracking a special pattern and not arbitrary features though, so be prepared for a big load of work.
Check this SO question for a first few hints, you'll find more information on the topic easily through the search engine of your choice.

I have been asked to give an estimate for an iphone game application.
I really have bad estimates for game application.
Can you share me links or stuff which will give me some idea of how long it will take me to develop the game.
I know this is very crude data, but some link that will give me database or share experiences about how much time other developers took for different games.
It really depends on your skills Amol.
Among other elements:
will you be doing the art assets, or are they given to you
are you designing the game, or just implementing it
do you "discover" Objective-C or are you an experienced iPhone or even Mac business application developer?
All these change your estimate drastically.
You also have to take into account the technique you will use:
pure OpenGL
Cocos2D
Unity
which partly depends on the previous questions.
Then you need to know which frameworks you intend to use:
Quartz
Core Graphics
Core Data
Game Center
and many other possibilities.
If the game is very simple, you probably won't need a database or a leaderboard. If you're implementing a huge tridimensional multiplayer online roleplaying game client, you might need a team to help you out.
You need to figure out the answers to all this before you can even put out a time estimate...

What do we need to build a multiplayer iPhone app? [closed]

I'm doing some work right now for a small startup who wants to build a multiplayer game for the App Store. The basic idea is that users of the game can look to see if anyone else is online and enter a 2 player turn based game.
I have no experience with this kind of thing, so I'm not responsible for that part but we need to know the right kinds of questions to ask potential hires. Does apple provide a framework for what we're trying to achieve? What kind of experience would you expect somebody capable of setting this up and maintaining it to have? I know we'll need an SQL-server to manage accounts and stats and such, but beyond that I'm not too sure.
How would you get started tackling this?
I'd start by looking at Apple's Game Center, which was added in iOS 4: https://developer.apple.com/devcenter/ios/gamecenter/
(You will need an Apple ID to see that page).
Game Center provides much of the framework you're looking for. (Note: it's less than a year old, so you may find limited experience with your interviewees).
Apple provides Game Center for turn-based multi-player gaming.
you can read about it here:

M very new to this field of iphone development.I need to make one app in which customer will be Purchasing ticket for movie by selecting the Location,Movie,Timing of show and seat.
Can anyone help me out in implementing Ticket Purchasing Part.
Thanks
Although you haven't asked a specific question and you say nothing about your experience in other programming languages I can give you some hints:
Look at the WWDC videos on http://developer.apple.com
Understand the Model-View-Controller paradigm
Make sure you really understood the Model-View-Controller paradigm
Start with designing your user interface first. Take your time for this. Make mockups on paper, each sheet of paper corresponds to a screen and play with it and show it to some colleagues and watch if they get what to do on each screen. You can also do this in Photoshop or Illustrator or omnigraffle, but in the early stage maybe paper is a simple option.
Build a mockup of your app on the phone itself. Using UIImageViews you can insert the digital screens made digitally to the phone and see how it looks like. Show this version to you customers. If they like the design and feature, you can go on coding.
Code everything
If you want to write a serious application it is good to invest a lot into design. The coding itself is much easier if you know how it will look like in the end, because then you can design the underlying model such that it will be great for your UI.
