Abstract
In this paper, we present a method to accelerate the speed of querying
and retrieving images in database. First we change the storing method:
pixels of an image are saved in Hilbert order instead of Row-wise
order using in traditional method. Then after studying the property
of Hilbert curve, we give a new algorithm which greatly reduce the
data segment number on the disk. Although we have to retrieve more data
than necessary, because the speed of sequential reading is much faster
than random reading, we have about 10% improvement on the total query
time which is showed in our simulation experiments.
