Face image manipulation iOS

Question

I would like some advice on how to approach this problem. I am making an app where users will be retrieving photos of faces from a camera roll or camera capture (assuming they are always portrait) and I want to make it appear as though the face images are talking (ex. moving pixels around the mouth up and down) using any known image manipulation techniques. The resultant animation of the photo will appear on a separate view. I have started learning OpenGL and researched Open CV, Core Image, GPUImage and other frameworks. I have been given a small timeframe and generally, my experience with graphics processing is limited. I would appreciate it if anybody were to instruct me on what to do using any of the frameworks or libraries I have mentioned above.

Answer 1

Since all you need is some animation of the image, I don't think it is a good idea to move the pixels around as you said. It's very complicated and the result of moving the pixels around might looks bad.

A much simpler approach is by using gif image. All you need to do is to make the animation of talking as a gif image and then use it in your app.
