I am beginner in android and I want to start a face feature detection program
I have already tried OpenCv but its too hard to handle. I want to know if there is any simple API that I can use
I recommend that you examine the basic article about Face Detection.
Then you can already see examples of code github. Good luck in your endeavor.
In addition, I easily found this article in Google and sample code was at the end of this article. I would recommend you to read about searching on the Internet.
I finally found what I really meant
it was the easiest and the best API for facial feature recognition and also face detection with happiness and open eyes probability
you can see here

Hi we are a small unit from Chennai having 3+ years of exp in Android programming. We have planned to move to Augmented Reality concept and we have decided to built the AR SDK from scratch! But we have no clue on where to start. We have already used KUDAN AND VUFORIA which are best at its sources but commercial. We know the principle behind the working concept of AR.
So what a SDK developer will plan before diving into coding? Kindly please dont close or downvote the question because as a 3+yrs experience we need some kind of more informations to achieve the task! Thanks for your support
First of all, you should know a bit more what this task require of you - you decided to do it from scratch without ANY effort estimation and cost estimation, because you do not know what is involved... This sounds like it might be a problem for you. I would strongly recommend making sure no AR open source SDK can assist you, since this is not a small project.
Now, if you insist... What I would suggest is to first set your goals - comparing to existing SDKs which you have examined, what do you want to achieve (performance-wise, memory-wise, API-wise, etc.).
Then, learn what feature-detection algorithms may be involved in order to achieve the required results, what type of system is required architecture-wise in order to meet the requirements. Design the architecture carefully, as the frame rate is the most critical issue usually on mobile AR apps. Also use the experience you got while trying to use other SDK-s - what was hard for you to use? What were you missing?
Once these are done, go and search for the technology to use - mainly, image processing library (such as OpenCV, and others).
Then, only then, you should start coding your SDK...
This is only the tip of the iceberg - you are up for a very big challenge.
I have been looking for this for ever on the internet, but I can't seem to find it:
I want to create an augmented reality app for Android using Qualcom Vuforia and Eclipse.
Compiling and installing the Vuforia sample app worked, but I just don't get the logic of all behind it.
Do you know a thinner/ lighter tutorial for starting with Vuforia? (NO UNITY!!)
It is not very clear what exactly you are looking for - a tutorial for starting with it is one thing, and understanding the logic behind it is another thing...
Anyway, you can start here:
Getting started with Vuforia.
What exactly it is they are doing would not be revealed, of course, as it is not an open-source library, but you can learn some things from the Articles section. They have explanations on several topics, one of which could also assist you to better understand what's going on there:
Natural Features and Image Ratings
It seems like every tutorial that I can find has a different, usually old, way of doing it. For example, even Google's LiveCard page has an example where they tell you to implement LiveCardCallback , however the link they give is dead, and that class doesn't exist in the GDK.
I also found a gdk apidemo on github, but most of those examples seem to be outdated?
Any good resource for an Android developer just starting out on Glass?
LiveCardCallback was renamed to DirectRenderingCallback in XE12. Thanks for catching one that we missed!
Third-party examples that you find online may have not yet updated to XE12, but the Compass, Stopwatch, and Timer on our GitHub page (and also found in the add-on's samples folder) are all updated and good examples of using live cards with high-frequency direct rendering.
i am upto recognizing the eye in an image (which is opened).The image is taken by the camera Activity in a tablet.By webservice i could connect it to postgres.But i dont know how i should consider those images to identify the eyes.when i searched i came across OpenCV but im new to it..is there any particular algorithm (name) to identify the eye..when i searched they said its possible in android with the help of opencv by simply importing some packages..but i dont know how to start and from where..can any one plz help me..Something supporting android will be helpful..
If my understanding is correct, there are few differences between the CV4Android library and the OpenCV C++ library. In addition, C++ code can be used by using the Native Development Kit for Android.
With that being said, OpenCV has a C++ tutorial that uses Cascade Classifiers to identify an individual's face and eyes and places a circle around each one of the eyes and a larger circle around the head.
The tutorial can be found here.
Edit: If you're looking for more information on the CV4Android and OpenCV C++ libraries, I'd recommend reading the reply to this question. Hope that helps.
My goal is to create a waving flag in Android using OpenGL but I don't have any clue on where to start.
Cloth modeling seems to make the neatest effect but I couldn't find any implementation for Android on the web.
I hope that someone would know some tutorials, resources etc. that could help me solve this problem.
If you know easier/other ways to create a decent looking waving flag, let me know. I'm open for everything.
Thanks in advance!
First result on google

A good tutorial about cloth simulation is from Jesper Mosegaard http://cg.alexandra.dk/2009/06/02/mosegaards-cloth-simulation-coding-tutorial/
The pioneer work on cloth simulation is from Darwin 3D http://www.darwin3d.com/gdm1999.htm#gdm0599
A open source project in Google Code provides a variety of algorithms http://code.google.com/p/opencloth/
All these works are based on C/C++ which is the natural programming language for OpenGL. As you are working on an Android project, you have to rewrite the algorithms in Java. After you figure out the mechanism, you should be fine. Good luck!
