No, the seed map must be integer (not more than 32 bit int), that's the only limitation. The data to be segmented can be anything, integer and/or floating point. But it does not make sense to use a pan band as seeds when segmenting the other bands. Seeds are typically the result of a previous run of i.segment or the result of a previous classification of the same data.
