Hi again. For the details of gift-add-collection.pl I would have to go into the code and currently I can't.

Well, we discussed this a lot in /199./ and /200[01]/ and came up with the thought that we rather want to add features like that in the client than in the query processor. In fact, from a HCI point of view it seems to be a good idea for the client to make the IR client a gathering space. Check out http://www.dcs.gla.ac.uk/~jana/research/publications/ECIR2006.pdf http://www.dcs.gla.ac.uk/~jana/research/publications.html Clearly, things like that are far beyond the scope of what image retrieval the server should do (at least IMHO). Having some of this work to be done in the server and some in the client seems like double hassle to me. So you end up doing: > The way it is currently working I would have to store the users query > into a db, send the request to gift, store its answer and remerge > something else out of the request I sent and the answer gift gave. Which seems not so bad, after all. > - The second thing is matching algorithm.

How can I tweak my system to try different > methods or make it more sensitive for shape / texture than color ? I remember having written a document about configuring and hacking the gift, which is surely too short, but maybe a starting point. Have you tried the separate normalisation algorithm or which one did you use when running the GIFT?
