Morphable Model of 3D Faces
nA face is represented by 2 vectors:
S0 =(x1, y1 , z1 , ……………..xn , yn , zn )T
T0 =(R1, G1 , B1 , ……………..Rn , Gn , Bn )T
where:
pixel at (xk,
yk , zk) have colors (Rk, Gk , Bk).
S0 is known
as the shape vector.
T0 is known
as the texture vector.
•To make calculations easier, we will use cylindrical coordinates where (xk, yk , zk) is equivalent to (hk, fk , r(hk,fk)).
