comment When is a cellular automaton “bidirectional”?
Well, no... now it's clear that I'm wrong at calling that 2D. Thanks. I guess that N = {-1,0,1} means the 1D neighbors at "left, self, right" and that N = {0, 1, 2} means "self, right, right+right". Right? (Kudos for the attitude, old man)

comment When is a cellular automaton “bidirectional”?
if CA reversibility is undecidable in 2 dimensions would it make sense for the authors of the paper to call their automaton "reversible"? (They don't call it reversible and the automaton is designed to work in images) I'm thinking that the "bidirectional" description of the automaton is unfounded.

Can I find out the state t, only knowing the state t+1, in a reversible cellular automaton?

@JosephVanName: I suspect the same, but I'm uncertain if the authors meant "bidimensional", English in the paper is poor.

I don't understand your neighborhood notation. Also, what do you mean by "two-sided", 2D neighborhood instead of 1D?
