Image warping: Lena image smile & upset

Hi all,

                    I just wanted to know if anyone could guide me by providing some sample code in MATLAB for modifying a 2D image, like a Lena Image, smile and upset. I understand that affine transforms are used and this is done by creating a triangular mesh for the face, but am really confused in this regard. Sample code will be greatly appreciated. Thank you in advance.

best regards,
