Abstract
The Alexandria project has been initiated to build a digital library
for map and satellite images. Designed for content-based retrieval,
the relevant information in each image is encoded in the form of a
multi-dimensional feature vector. Though representing images by feature
vectors greatly facilitates user queries, indexing these vectors degrades
performance when the number of dimensions is large. We consider 2 popular
techniques (DFT and SVD) to reduce the dimension of feature vectors, and
study their retrieval performance with respect to recall and precision.
We find that though SVD generally out-performs DFT, DFT compares favorably
in a limited range suitable for browsing large image databases.
