CFA Architectures Review

Vision Systems Design published a brief review of the recent attempts to improve on Bayer CFA:

(a) Bayer CFA classic,
(b) Truesense's RGB+White pattern (wrongly shown above as RB-W),
(c) Aptina uses Clear pixels instead of Green,
(d) Fujifilm's X-Trans CFA increases the randomness of the pixel arrangement to 6 x 6 sets,
(e) Panasonic proposes a method that replaces these color filters with inorganic color splitters.
