2.(15 points) a) (5 points)Discuss the rotational invariant LBPs. b) (10 points) Consider a 4 x 4 corner pattern: 60 60 60 60 60 30 30 30 60 30 20 20 60 30 20 20 Compute the Rotation Invariant LBPs of the 2 x 2 pixels, marked in red at the center. Show that they are invariant after a 90-degree clockwise rotation of the whole pattern. 2.(15 points) a) (5 points)Discuss the rotational invariant LBPs. b) (10 points) Consider a 4 x 4 corner pattern: 60 60 60 60 60 30 30 30 60 30 20 20 60 30 20 20 Compute the Rotation Invariant LBPs of the 2 x 2 pixels, marked in red at the center.
