I need a help to develop a small application on Augmented Reality.I have spend almost a week trying but with no proper solution.Tried some sample code but still not successful.
I have seen many videos and want to develop something like that.
for example my code should detect only square or any particular shape.And then after detecting the square and another Image should appear on the screen.
Please help me out.
This stuff is hard, but most new cool things are until they are no longer cool or new.
You can play with AR Toolkit until you are familiar with the functionality and then attempt to dive into the setting and mess with those, then maybe look at the source.

I am trying to make a photo editing application for iOS, but am not sure where to start looking. I have attached an image made in Word... that hopefully simply depicts what I am trying to achieve. It will involved manipulating individual pixels of a shape/image and masking/clipping. WHow should I start and what resources are available to me other than the developer docs?
Cheers
If you are not new to programming I would suggest a trial and run kind of approach. If it was me, I would follow a approach like this
Figuring out what to do/ what not to do
Do I need to develop the tech I want from scratch or can I use some pods ?
What are the good reads and example apps - (Try this)
Development approach
Build a photo gallery to pick images from
Build a EDIT mode screen
Get set of template overlay images
Figure out how to overlay them on top of each other
Export the final picture as one picture
The developer documentation is essential when it comes to learning new APIs, but sometimes it can be a little overwhelming. You can try reading raywenderlich.com tutorials on Core Image first to get an idea (link here) or find a book on computer graphics. It is essential to understand at least the underlying techniques to efficiently program image processing code. In many cases you'll find there is a more elegant technique than just looping on pixels and modifying one-by-one.
Then you can continue with reading on image compositing using core image for example.
I have planned to detect an image in a news paper play the video relevant to it. I have seen several news paper reading AR apps include this feature. But i couldn't find how to do so. How can I do it??
I dont expect any code. But like to know what are the steps I should follow to do this. Thank you.
You need to browse through the available marker-based AR SDKs - such SDKs let you defined in advance the database of images you would like to detect and respond to, and once any of these images is detected during runtime, you get some kind of an event with data on the detected image.
Vuforia is considered a good one and it has good samples, so it is supposed to be easier to start with. You should also check out Kudan, and there are more.
This is a pretty basic question and doesn't really need much depth for an answer. I was just currently interested in developing an app for iPhones and after learning the swift2 language from the Mac site, i was just wondering which API I should use.
I did some moderate research, and so far spriteKit seems like the way to go (bit of a hassle if I want to port it over to android, but not impossible). But I was just wanting to make sure it's the right way to go.
The app idea revolves around keeping track of some form of progress and being able to use this data to generate graphs for the user? I'd also like to add some image functionality to the application as well. (similar to the health app and how it measures distance walked?)
I know this sounds vague, but would spriteKit be able to do these things? Or is there another API worth having a look into? (I've checked out metal and sceneKit as well, but leaning towards the more 2D type apps)
From my point of view using spritekit for this is overkill.
There are some greats frameworks to do graphs like charts :

Spritekit is more gaming oriented, if you want a "simple" app you don't need it.
I don't think SpriteKit is the right API to accomplish your problems.
SpriteKit is all about moving and manipulating images on the screen. I am quite familiar with the SpriteKit API.
I do not see any help for generating graphs or something like that.
Also it is not the right API to display a proper interface for "serious" apps.
Nowadays, I wanna do some research of augmented reality technology.Especially, I would like to match a 2d image and a 3d model.And then, I will see the 3d model if scanning the 2d image. What's more, I know that there are a lot of SDKs(like metaio,and wikitude) and software can realize this in mobile app. However, what I want to do is realizing this in a website. I hope the people who use this don't need to download a particular mobile app, but just open a website and then scan a picture.
So, until now, I's like to know that,as the tile asked, can AR be realized in a website? If yes, how can I do it or is there any software like Metaio Creator to do this? If no, why?
Thank you for anyone who would like to answer my naive question.
May I recommend you our completely webbased AR & VR tool holobuilder.com by bitstars.com?
It supports 360 degree photospheres that can be enhanced with custom 3D models and then directly be embedded into your website as iframe, it has native support for stereoscopic view mode and much more.
For your use case you could have a look at the lower part of this blog post where you find information and an embedded example presentation with photosphere imagery containing 3D elements:
http://heyholo.com/google-pushes-vr-great-for-tools-like-holobuilder/
If you want to start creating I recommend the beginners guide:
https://medium.com/#maxspeicher/the-definite-guide-to-holobuilder-3b62a54d303e
The cv feature tracking you requested can not yet be realized without any apps/browser. But what you can do is realizing perspectively correct displaying 3D elements into the camera image and move with sensors. Should be as performant as within the player app.
We hope that it can somehow help you in pushing your research and we would love to read your feedback. In case of any questions please do not hesitate to ask, here or on any other contact channel!
I have followed the MSDN Platformer tutorial and made a variant with it.
However, I want to make a Platformer like the Super Mario games. Although I prefer to make a game with a basic level, instead of a side scrolling level.
I've read certain documents about using Tile grid to create my levels. Are there also beginner/full tutorials available to create a start?
Basically need help with the first steps of setting up a level.

I have not used XNA for about 6-7 months, but back when I was 'playing' with it, I was working on Windows Phone 7 games and learned a lot from this blog over here. His tile engine worked pretty good for me.
Although it looks like it is for RPG-like games, take a closer look at the examples, there is a 2D platformer example there too.
You must read this, otherwise nothing will make sense :)
