If you really want to use i.maxlik, you have to create as many raster 
layers as you want to have variables characterizing your objects. Then 
you select a series of these objects as training areas and then you can 
run i.gensig + i.maxlik.

But I think that the machine learning approach, using Pietros 
addon-modules, is probably more efficient.
