Is there any filters available in ios to convert a image to cartoonistic image like exactly in the above picture?
For a much faster solution than ImageMagick, you could use the GPUImageToonFilter from my GPUImage framework:
It combines Sobel edge detection with posterization of the image to give a good cartoon-like feel. As implemented in this framework, it's fast enough to run on realtime video from the iPhone's camera, and is probably at least an order of magnitude faster than something similar in ImageMagick. My framework's also a little easier to integrate with an iOS project than ImageMagick.
If you want more of an abstract look to the image, the GPUImageKuwaharaFilter converts images into an oil painting style, as I show in this answer.
Try to use imagemagick for iOS http://www.imagemagick.org/download/iOS/
Of course you need some serval hours how to use imagemagick for iOS.
But then you should also look at: http://www.fmwconcepts.com/imagemagick/cartoon/index.php
and maybe also on:
http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=11140&start=0&st=0&sk=t&sd=a
This Core Image filter section in the iOS dev library, possibly combined with the script referenced by Jonas and a little luck, might get you where you're going. Not sure, having never used either of these technologies.

I need to detect something like a barcode but colored on live video (I don't necessarily need tracking, it is optional).I could use OpenCV but I thought it is worth a try asking here. The problem with openCV is that I am not very familiar with the whole concept of image processing. The other problem is that I use swift in most of the time, and however I could write an Obj-C wrapper with the help of google, the fact that OpenCV is written in C++ does not help at all, so maybe it would take too much time to use OpenCV.
Do you know any SDK-s that could help me in that? (It is not a problem if it is not free)
EDIT:
To be clear. By "something like a barcode" I mean that it is colored and instead of the width of the bars the colors are what metter.
I'm trying to write an app that recognize a logo saved in app bundle and readed as UIImage. I have did a search before make this question, the only free solution seems to be OpenCv. I have tried it in a demo i had download from toptal_logo_detector . The demo works and i can find my logo everywhere i place it. Anyway the camera is very slow, too slow to use it in a real app. Maybe there's a way to optimize it, but my question is another.
I have to recognize a vector logo (always the same logo) centered in a white background ,something like this wifi logo:
My only solution is the complex OpenCV? There's a free and simpler way to achive the result: YES here there's your logo/No there isn't ?
I found this tutorial (with project download) that does what you want using OpenCV
Is it possible to use Vuforia without a camera for image tracking?
Basically I would like a function I could call with an image as a indata parameter and coordinates of a image target as a result. Does that exist?
It is unfortunately not possible. I've been looking for such an option myself several times while working on a Moodstocks (image recognition SDK) / Vuforia mashup (see these 2 blog posts if you are interested in it), but the Vuforia SDK prevents the use of any other source than the camera.
I guess the main reason for this is that the camera management is fully handled internally by the Vuforia SDK, probably in order to make it easier to use as managing the camera by ourselves is at best a boring task (lines and lines of code to repeat in each project...), at worst a huge pain in the ass (especially on Android where there are sometimes devices than don't behave as expected).
By the way, it looks to me like the Vuforia SDK is not the best solution you can find for your use case: it is mainly an augmented-reality SDK, focussed on real-time tracking, which imply working with a camera stream... so using it to do "simple" image recognition looks really overkill!
I am currently working on Appcelerator (Titanium) and now I want colorize image in APP. Like I have an image and I can able to change its color through Hue or saturation just like in Photoshop. I have searched too many things but still nothing found in working condition.
Any help would be highly appreciable
Probably the best architecture is to create a webview in which you have a canvas tag, then you are able to use any canvas image manipulation library you wish. There are a number of them, but here are a few.
I have got one image like this
to only black and white colored image.
And I come across this ImageMagick resource
Does this can be used to generate black and white image from the above given image?
Does it is good to use this one?
If it is good one then does there is any documentation or tutorial on "How to use?".
UPDATE
SO GOT THE BEST SOLUTION FROM #ale0xB's SUGGESTION.
No third party api is required for doing this as apple's COREIMAGE.FRAMEWORK is the best for doing what I want to do. It's filters are working like charm :)
Thanks for the suggestion :)
I use this image filter. And it is great in speed and provides great output :)
Why would you want to use imageMagick instead of the standard Core Image to produce black and White images? I haven't used it before, but I doubt it's gonna give a much better performance than the native framework when it's just about creating a filter.
Since iOS 6 you have it really easy, have a look: Core Image filters, specially to CIColorMonochrome, which is the one you may be interested in.
If you're playing with images in your app, this is definitely worth checking: Core Image Programming Guide
