The SURF descriptors are 64 dimensional vectors, and I think SIFT is 128 dimensions, so it's definitely an improvement. But I don't think it really changes the problem of how do you index large-dimensional vectors. I did see this paper, which looks promising: MKL-Tree ftp://ftp.cse.buffalo.edu/users/azhang/disc/springer/0558/papers/2453/24530914.pdf Marc _______________________________________________ Geowanking mailing list [email protected] http://geowanking.org/mailman/listinfo/geowanking_geowanking.org
