I just wanted to know that,
As bar-code scanner works in Android.
Is that possible to make ocr based application in android which will recognize the characters on the go only..
Means As I start my camera in application, it should start doing its work instead of taking a picture and then recognize...
Thank you in advance.
You can use OpenCV for Android. For on the fly recognition you can see how BarCodeScanner implements it here

I was trying QR Code scanner in a React Native project. I have used these two libraries -
https://github.com/moaazsidat/react-native-qrcode-scanner
https://github.com/ekreutz/react-native-barcode-scanner-google
Both of these libraries doesn't scan QR Code from an angle. Phone should be exactly in front of QR Code then only it scans. However, same library works very fast and from any angle in iOS. Is it a limitation of android camera? Can we do something to achieve same behaviour in Android too?
I had a similar problem while developing barcode scanner for my app, I tried different libraries for Android, however Mobile vision(API developed by Google) pretty much solved this problem for me. Give it a try
I am working on an android application which detect faces in real time and for that i have to make a camera to scan faces but i do not want to give a capture facility in that camera and after detection the next option of filters will come automatically. So, is this possible?
Yes of course,it is possible and OpenCV do that all for you... follow the given links:

I am looking to develop an application that will allow the user to launch the camera and use it to scan what the camera sees for a certain logo or word.
I have had some experience using the Zebra barcode scanning library so I am able to launch the camera and scan for a barcode fine.
The issue comes when I try to scan for a logo. Is it at all possible to scan for the logo in real time with the camera or would I have to have the user take picture and then scan the newly take picture and compare it with the logo that is being searched for?
Scanning for a logo is an entirely different problem. The Zebra Library has been designed specifically to recognized barcodes and qr codes anything outside of that scope and it won't be able to interpret anything. You can scan for logos in real time or on the cloud. Amazon does this with their shopping application so that you can research what you find at the supermarket or at a friends house.
There are companies that can offer you Image Recognition as a Service:
https://www.clarifai.com
or you can look into your own open source implementation
opencv.org/
There's examples for OpenCV for Android but you're going to need a bit of background on Machine Learning and Computer Vision before you get started.
I am to start working on an Android Custom Camera App. I just want to know is there any way to add the following features to my app:
Beauty Level
Red Eye Removal
Acne Removal
I just want to know that if it is possible, can someone suggest or give me any idea how can code it into my app.
Though I am familiar with Android Camera API functions, and worked on several simple custom camera apps.
Thanks in advance
For beginning, you can use FaceDetector to detect faces in the picture.For example , you can remove Red eyes by searching for Red pixels in the picture and try to decrease red level of them.And also , you can use OpenCV for detecting eyes.I found a sample for eye detection in Here
Hello im trying to make my own special custom code scanner. My app's render a special custom barcode and I need to make a very simple scanner that will take whats currently being seen with the camera and quickly process it to decode the barcode. So how can I grab the frames from the camera and use them as images without pressing the "take" button.
check the open source project. It give bar-code without click take photo button.

Thanks
