Face recognition using OpenCV in android?

Question

I am able to detect faces using open cv but I don't know how to process face recognition.

I googled a lot but I didn't find any articles or blogs that can guide me.

Can someone help me to develop face recognition App in android?

You can always use JavaCV that is a kind of wrapper for the native OpenCV functions:

See: Face Recognition on Android

In order to get everything working you have to extract some .so files to your libs folder in the project:

Follow the instructions on this page

1. Go to File > New > Folder, select your project as parent folder, type "libs/armeabi" as Folder name, and click Finish.

2. Copy javacpp.jar and javacv.jar into the newly created "libs" folder.

3. Extract all the *.so files from javacv-android-arm.jar, opencv-2.4.6.1-android-arm.jar, and ffmpeg-2.0.1-android-arm.jar directly into the newly created "libs/armeabi" folder, without creating any of the subdirectories found in the JAR files.

4. Navigate to Project > Properties > Java Build Path > Libraries and click "Add JARs...".

5. select both javacpp.jar and javacv.jar from the newly created "libs" folder.

Source: https://code.google.com/p/javacv/

Include javacpp and javacv in your libs folder: https://code.google.com/p/javacv/

Find the required jars in javacpp after download and extract the required SO files (yes, you can open the jar with WinRAR)

Compile and build the code experimented in: Face Recognition on Android

And here you go! It worked for me, so I'm sure it will work for you!
