Android Camera preview with funhouse mirror effect

Question

I created a android small app that uses the front facing camera to shoot a selfie. But what i want to accomplish is a funhouse mirror effect.

I searched the internet trying to find a solution or a way to do this but i am guessing i am searching for the wrong terms here:

Sample Image

Can someone push me in the right direction or how this is made? I searched for morphing, distortion etc.

What i have right now: A basic camera app wich is saving a taken photo using the Camera2 API in Android SDK 23

Answer 1

Just only Camera2 API are not enough to develop an app which is like mentioned you. You should use computer vision libraries such as OpenCV or OpenGL .

First of all, please check it out for creating theoretical background.

Here is an example application which is using OpenCV and it is about funny effects.

This can be another reference application which is about fun house effects and it was developed by using GLSL.
