Do you mean that unordered_map can automatically instantiate a hashing
function for any type of pixel? I have tried this:

boost::hash<pixel_rgb8_t>()

And VC11 will spit:

error C2664: 'boost::hash_value' : cannot convert parameter 1 from 'const
boost::gil::rgb8_pixel_t' to 'std::type_index'

Thanks.
