Do somebody tried to recognize objects via Android camera? I want to write an application,which can recognize a products in a market. It can be by existing image for comparing or text detection.
I've tried to start with OpenCV, but there not a lot of useful examples.
Found SentiSight Embedded SDK.. The same problem, cannot find how it is works.
Could someone recommend a good solution?
Thanks for everyone.

Using Tensorflow lite I am trying to find a way for facial recognition (not detection) using camera given picture.
I googled everything related to this but all are detecting face.
I followed these links:
https://firebase.google.com/docs/ml-kit/android/detect-faces
https://medium.com/devnibbles/facial-recognition-with-android-1-4-5e043c264edc
Any help will be appreciated.
Thanks a lot in advance.

I'm fairly familiar with android application developpement and have created quite a few apps within Android-Studios. Now I'd like to do an app wich can detect a A4 paper in an image and read it's content. Can you name me a couple of libraries/API's? I've checked out OpenCV and Vuforia, but couldn't find something with this particular problem.
Thanks alot!
The best (free) possibility for OCR (Optical Character Recognition) would be Tesseract Engine.
Please note however, that you'll need some background in image processing to get reasonable results.
There are libraries that do the preprocessing for you, but most of them are commercial projects.
I want to develop a Camera 2 kind of application. So i just wanted to know how to apply live effects to android Camera .Is there any android library for that? plz help me to solve the issue.
thanks in advance....
What have you tried? I assume by live effects you mean shown on the preview.
You can try what the answer here suggested, but any sort of complicated filter implemented in java is going to slow things down. For good performance you'll probably have to write some native code to process the previews. The good news is, if you're writing NDK code you can make use of libraries like OpenCV to do the filtering for you.
In my application I'm going to implement an image search like Google image search. Only difference is here I'm searching only for human faces. Here's how it goes..
user take a picture of a person using the camera.
my app should identify the face of that person and get details from the image regarding the face (eg: colors).
Using those details app will do a search in the image database for similar faces.
Finally it'll display results to the user.
So I want to recognize faces using Android face recognition class and select that recognized area and save the details of that face into an array or a database.
I got few questions on above scenario.
what are the things I need from that image to do a proper image search?
Can I do it only using colors?
Do you have any idea on getting pixel details from that recognized face? I know how to do it on bitmap images. But i'm not sure that method still works with the face recognition class.
Can anyone explain those thing to me please?
Use OpenCV's Recognition API.
I wrote a bit about how to set it up in another question.
I recommend you too to use OpenCV functions, they are well optimized for face detection and recognition .
for recognition, you don't need to colour processing.
Since you develop your application on Android, you can use OpenCV4Android
Here there some helpful links, that let you have a good idea to start:
Face Recognition on Android
Here you find a useful tutorial for face detection and recognition
http://www.shervinemami.info/faceRecognition.html
I also recommend you to apply the detection api that already implemented in android stuff:

In order to prepare a clean and a proper face database, which in turn enhance the goodness of recognition results, don' forget to align faces

Try and test already benchmark face database, to evaluate your implementation:

I'm interested in developing Apps with Unity 3d and I have a project coming in that could use it but I need a crash course.
When I started to develop for iOS I was able to find an awesome 4-day course and I can't seem to find anything similar for Unity 3d.
Can anyone recommend a similar course?
There are training videos here:
http://www.design3.com/ with developer/designer community
http://www.3dbuzz.com/

Well, about interactive courses, I know about this one in US:

If you are a student or teacher/faculty I'd suggest to go to http://www.studica.com/software/tutorials/Unity-Training.html
You get all kinds of student discounts if you qualify.
