Could someone help explain why, in the example image the following transformation occurs (in the periods separating the R and C, and after the C):
..... ..... .###. -> ..... .#?#. ..#.. ..... .....
Surely the the cell labelled '?' will be culled at step 1:
- It is black with 8 neighbours - B = 5 (2 <= 5 <= 6) - A = 1 - At least one of P2 P4 P6 is white (P6 is white) - At least one of P4 P6 P8 is white (P6 is white)
Why isn't it whitened at step 1?
