Red dots = Center of the left eye (L), Center of the right eye (R), Center of the mouth (M)
Purple line = LR line
Red line = horizontal line crossing the middle of L and R
Yellow line = vertical line crossing LR at Mx
Blue line = LM and RM
Green line = distance between X-coordinates L and R
Given these data, is it possible to determine the yaw, step and roll of the face?
All I have is roll:
Roll = angular difference between left and right eye
Knowing that L, R and M are all moving relative to each other, should it be possible to correctly calculate yaw and pitch in 2D space?
, - - LR ( )
