A METHOD OF MAKING LOOKUP TABLES FOR HILBERT SCANS

Recently applications of Hilbert curves are studied in the area of ima ge processing, image compression, computer hologram, etc. We have prop osed a fast Hilbert scanning algorithm using lookup tables in N dimens ional space. However, this scan is different from the one of previousl y proposed scanning algorithms. Making the lookup tables is a problem for the generation of several Hilbert scans. In this note, we describe a method of making lookup tables from a given Hilbert scan which is o btained by other scanning methods.
