Data Structures for CurveIx

Ci a mapping function for each of the m different space-filling curves (i=1..m)
Db a database of N d-dimensional feature vectors; each entry is a pair:

(imageId, vector)

imageId forms a primary key

Index a database of Nm curve points; each point is represented by a tuple

(curveId, point, imageId)

the pair (curveId, point) forms a primary key with an ordering, where point = CcurveId(vimageId)

vq feature vector for query q
