Im exploring possibility to apply a CA to a portion of a region in an image.

Think that I can process an image to identify a region, as an example, a green area. I would like to confine that area, and apply a cellular automaton to it.

I am trying to help myself with demonstration (E.g. https://demonstrations.wolfram.com/2DCellularAutomatonOnATriangulatedSurface/ )

but instead of a complex manipulation, I would like to understand how could you "confine" the boundary of a region to map the automaton - and stay only in it.

In CellularAutomaton[] Options BoxMatrix[] is mentioned, but there is not an example of how to use BoxMatrix with CellularAutomaton: not clear where to start.

Should "pixelate" a region with a box matrix first?

How would you apply a Rule to the green area in this Satellite image ?

Conceptually, I tried something like:

img =[(* img in attachment*)];

MorphologicalTransform[Binarize[img],184,2]

but I don't want to apply a rule to a 3x3 neighborhood (MorphologicalTransform) - I want to apply a rule to a subregion I can extract from the image.

I thought about:

(* img color distance from the green areas *) cd = ColorDistance[img, RGBColor[1/255 {79, 93, 56}]]

(* binarize the img *) RegionBinarize[img, Binarize[cd, 0.3], 0]

Now that I "isolated" the green areas, how could I apply a CA rule to it?

(Comments about better ways to handle color isolations are welcome, although focus is on applying CA to them).

thank you and have a nice.. Christmas Holidays!
