註釋

In this paper, we present a method to accelerate the speed of querying and retrieving images in a database. First we change the storing method: pixels of an image are saved in Hilbert order instead of Row-wise order used in traditional method. Then after studying the property of Hilbert curve, we give a new algorithm which greatly reduces the data segment number on the disk. Although we have to retrieve more data than necessary, because the speed of sequential reading is
