I am creating an iPhone application for image morphing using OpenCV 2.4.3. I am able to do the morphing but some noise/distortion is also getting introduced. I am not able to identify where the source of this noise or how to remove it. Please help me out if someone has faced any similar issue or has any experience in image processing. I have attached a sample input/output for reference. Thanks in advance :)
What I actually need is something like this:

I tried to track motion in Matlab by using this tutorial (http://www.mathworks.com/help/vision/examples/motion-based-multiple-object-tracking.html) and it works fine but it implies video as source to work.
I wanna know if it's possible to track motion by using the same tutorial but in real time by using camera as source!
Everything is possible, just please try to find some stuff by yourself before asking here.
I think you may find the information you need in this link:

Alternately, you could of course just store the camera output as a (very short) video and continuously analyse that instead.
As of release R2014a, MATLAB includes support for USB webcams. If you have an older version, or if you want to use a high-end camera, you would need the Image Acquisition Toolbox.
Once you are able to get frames from the camera, you can reuse almost all of the code in the multiple object tracking example. You would only need to rewrite the readFrame function with code to get a frame from the camera.
I am new to iOS projects. In my current project, I have to process an image which contains LED object. I want to extract the LED object status (on/off) from that image in iOS. Is there any open source library to process the image for my scenario. Please help me.
Thanks in advance.
I think there is an opencv port for ios.

You could use OpenCV. But honestly for what you want to do, doing it yourself would be way easier.
I am working on a project of mine which requires a webcam and MATLAB. I have a Logitech Webcam, and I dont know if I could talk to it through MATLAB because Im trying to work with images and image processing, so I just want to know if there is a way to find out if the webcam is combatible with matlab or if I need to get some other type of webcam to get the job done, if I do need to get another one, it would be helpful if you suggest a certain cam that is cheap and available around.
Thank you.
I've used several Logitech webcams with the Image Acquisition Toolbox on Windows. You'll find a list of supported hardware here.
I've googled around for this however the only thing i've properly come across is the simple-image-processing library on Google Code, however i think the project is dead! Does anyone know of any libraries/frameworks, even tutorials on image-processing for iPhone apps?
Apple has some sample code here that shows how to do some simple image processing like saturation and hue adjustments.
I want to build a similar app as fatbooth and want some ideas on how to do this. I googled for Image morphing in iPhone but didn't find anything. Should I use some server side language to morph Image?
Any help would be much appreciated!
Thanks

The only language you can really use is C# or c++. the maths is very complicated although I am sure you can get a book or two that cover image manipulation.
I don't know if there is an open source morphing framework, but that is your best option - it doesn't have to be specific to the iPhone, but the integration will be hard.
I don't know what you mean about server side, unless there is a server you know of that does it and you want a wrapper around it
For starters, take a look at displacement mapping: http://www.imagemagick.org/Usage/mapping/
Basically, you use grayscale images to bloat/shrink/squeeze/etc parts of a person's face. I made an app called FaceCraze which had to implement a poor man's FatBooth as part of the face transformation, and I used grayscale images very similar to the examples in http://www.imagemagick.org/Usage/mapping/#spherical
edit: You can use the ImageMagick library in your iOS apps too: Link
