opencv - iPhone Photo Smile Manipulation Applications -

-

i'm trying create iphone application allows user take photo of smile, drag , drop new smiles, small predefined list.

i know there lot of photo manipulation apps , have seen similar concepts allow smile manipulation, not quite looking for. problem knowing start. how can create effect? opencv iphone port best way go? or perhaps using opengl? willing research, find experience goes long way, advice or insight appreciated.

that's pretty cool application. i'd recommend type of dense optical flow type alignment method strike balance between global consistency , local consistency.

in short, you'll want generic mouth shapes in gallery. then, can crop user's mouth region , warp gallery shape show smile in shape like.

ce liu's optical flow implementation might interesting point start. should able port reasonably easily.
