iphone - How do image distortion applications like the 'Booth' series work? -

I just wanted to know how to work on all iPhone / iPad 'booth' applications (like FatBooth, BaldBooth, SkinnyBooth) How do your image distortion?

This image is processing.

First you need to find the person's face.

Then you process the face with an algorithm or a layer for the face.

To get you the OpenCVI Framework () recognition for the face (^^) and OpenCivi forums.

Good luck.
