Re: GIFT Indexing

Hi,

it seems that the total number of extracted and stored features in the 
inverted file is too large in this case (seekg(-2147483632)).
I have worked with databases of around 100'000 images and it worked 
perfectly fine.
I have no quick fix for this at the moment.

Cheers, Henning
