Face Recognition integration - android

I want to integrate Face Recognition in Android.
1) First time user will sign up by scanning face (Will stored on Server/local)
2) Next time when a user tries, it should detect the user from the stored image.
I tried exploring Face Recognition of AWS but ended up with confusion in setting up.

there are multiple ways you can do this.
there is a simple library for this purpose in android called FaceDetector. you can use that for face detection only.
there are also more advanced libraries like OpenCV which is available for many languages including java and android. but I recommend if you are not familiar with android NDK or computer vision try sticking with the FaceDetector library.
note that if you start with OpenCV. it is going to be hard for you at first because you are entering a field called computer vision which is a branch of machine learning. and immediately you will feel it that you're walking in a completely new territory

Android: Face Recognition even with mask using OpenCV or some other library?

I am looking for a solution to develop an attendance system. The problem is I cannot find a good library to work in (or maybe I don't even know). I want to implement Face Recognition based on the previously saved faces when a user signs up. I also want to recognize a person even with a face mask on. Can you help me by providing a path to use?
I have a sample Application https://play.google.com/store/apps/details?id=com.ttv.facedemo
This is implemented using FaceOnLive SDK which is paid, I want to implement the same feature using OpenCV.

How to rapidly prototype an image recognition application using Machine learning & neural network?

Known that I'm very new in Machine learning.
I was thinking about a real world example of using Machine Learning
and Neural network in an application and I want to try it with a
mobile application who can handle image recognition with the front
camera after make an image of something(A cat for exemple).
I really need advice of tools to use to rapidly make a prototype of this application with a python backend that I will call via rest.
Thanks in advance.
I suggest if you are new to the machine learning algorithms, that you use an API from Google or Microsoft and get in touch with the flow and how it works .. Once you understand what are the inputs and outputs, you can try to replace the API for you own neural net, try to train it properly and collect results ..
Machine learning is not an easy concept and if you start big, there is a good chance that you'll get discouraged before you finish building it ... The API will provide you with a functional prototype very quickly and thus help you stay motivated to pursue it more ..
But to answer your question more directly, TensorFlow by Google is probably the most sophisticated tool for machine learning in general right now..
There is an excellent course for deep learning with TensorFlow made by Google on Udacity ..
You can follow PyImageSearch. It has lot of stuff related image processiong like face recognition and license Plate Recognition system. It also use neural networks.
Use an image recognition API, like google vision.
It is easy and fast to put in an application, and a lot more effective if you do not have experience and ressources in ML
I have done something similar for our company website. It is based on caffe though.
You can go through the source code here
However, it is a segmentation demo. You need to modify it a little.

App of image detection in xamarin

I want to make an app of image recognition and i need help of where to start. What i need is someone to explain me these few things
Wich offline libraries are the best to use with xamarin for image processing
in case more performance is needed, best libraries for Image processing iOS and Android to work them separately.
It does not matter if the library is in C or C++ what i want is documentation to follow
My idea of best is.
Well documented.
Easy to implement on the platforms xamarin or individually
The main functions i am looking for are for object recognition in an image NOT at runtime with camera
Also i want to add if is there any well document of fundamentals of image procesing and edge detection.
Thanks
Depends on what you want to do - image detection is a big topic.
A couple of places to start are:
Microsoft cognitive services
https://blog.xamarin.com/performing-ocr-for-ios-android-and-windows-with-microsoft-cognitive-services/
This is an on-line service and can do OCR, facial recognition, even describing what is in an image.
OpenCV
This is a fully featured computer vision library available in C++ with iOS and Android wrappers you can bind to use form Xamarin.

Face Recoginition Android/iOS

I want to do Face recoginition (Not Face Detection) in my Android and iOS app. I have studied a lot on Web and found following possible solutions:
1.) openCV: I don't want to go into writing my own API using this. Also, I don't have prior experience in JNI for Android.
2.) Betaface API So far this is good.
3.) Sky Biometrics is also Good.
Now, I am searching for the solution from 3-5 days and came to know that I can use above API (so far I have decided to purchase license for Sky Biometrics). And this API will provide me a list of Features for the faces it recognised.
But, Now I am confused That how to use these features and save in my local data base to recognise faces from the pictures.So My queries are following
1.) How to convert Face features to Actual working Face recognition API means What is the actual algo or solution I can use to merge diffrent face features of a same person to identify him correctly.
2.) Uploading images and then creating database for Face-features set is a very time taking process. Do any one knows any Android/iOS Face Recoginition SDK to do this so that I can do this accurately and timely with no or less time taking process.
3.) Both solution-2 and 3 can be used with Images. Is there any other solution is available which can do the same with less efforts but with more accuracy.
OpenBR may be also interesting for you: http://openbiometrics.org/
Finally I am using Rekognition API. And this is good enough to serve my purpose.

Real time traffic sign recognition in android

I'm trying to develop a mobile app for traffic sign recognition and i want it to be in real-time. I'm trying only to detect circles signs and to find out what sign is in order to notify the driver. I want to know what is the best method I should use. For now I've tried using java and opencv to find the circles in an image (using HoughCircles) but is not quite what I've expected - a lot of signs aren't identified. Then I tried to use opencv for training it to learn the signs - to obtain an xml trained classifier, but it takes too long and to be functionally I need a really large amount of data. I don't know what to do ... Thank you in advance.
I found this work with some research: https://www.academia.edu/4950526/Traffic_Sign_Recognition_system_on_Android_devices
