I have to simulate facial expressions on a face image ( say open mouth ). For this I first extracted the facial feature points and found the corners of the lips. Now I need to deform the image by moving the points down.
In the above image I need to move the points ( 2 ) and ( 3 ) to some distance left and right respectively. And point ( 18 ) and ( 19 ) littele bit down. So that I will get an expression like opened mouth.
1) Is this the above way right to proceed to simulate facial expression?
2) If it is right how to move the points and create a new image in opencv?
