Please state how large the images are, it isn't obvious what for example 
global Moran's I would give you. Could you answer the same questions of 
subscenes? Are the data likely to be non-stationary? How are you reading 
the data into R, how are they represented? Even geostatistics will be hard 
with many observed points, easier with many points to predict to.

You have looked at rimage, I suppose? Could you extend that?
