Ok, we agree that you can not average them as bitmap. So you need a 
model. Which means extracting parameters from the fingerprint in a way 
that they can be averaged. With vector I assume that you think that you 
can normalize all fingerprints and then at some sampling points compute 
the angle of the closest line in the fingerprint or something like that. 
Then you can for each point define the average direction of 
fingerprints*. Only, what you get is the average model not an average of 
the input. Don't confuse a model with reality.**
