Spatial ordering is a transformation relating an n-dimensional voxel to a set of natural numbers. Interest in the Hilbert order (H-order) has been high because of its desirable performance when applied to image processing. In this correspondence, an encoding/decoding algorithm for the three-dimensional (3-D) Hilbert order is presented.
The higher-level graphics language LIG has now been operational for over two years. The language has proven to be easy to learn and easy to use, as attested by a number of programmers. Through its use, many improvement possibilities of the syntax and the supporting subprogram system have shown up. The experimental design of a higher-level special purpose… (More)
