Rank Theorem (2)
•If the rank of
observation matrix M is 3, assuming there are two shape matrixes Si and Sj,
the shape S and projection matrix
P and
be arranged as follows:
–Due to the
fact that the rank of P is 4, the rank of S must be 3.
For 3D shape, this means Si=RSj so that Si and Sj are for the same action.
