The sampling lattice used to digitize continuous image data is a
signi?cant determinant of the quality of the resulting digital
image, and therefore, of the e?cacy of its processing. The nature
of sampling lattices is intimately tied to the tessellations of the
underlying continuous image plane. To allow uniform sampling of
arbitrary size images, the lattice needs to correspond to a regular
- spatially repeatable - tessellation. Although drawings and
paintings from many ancient civilisations made ample use of regular
triangular, square and hexagonal tessellations, and Euler later
proved that these three are indeed the only three regular planar
tessellations possible, sampling along only the square lattice has
found use in forming digital images. The reasons for these are
varied, including extensibility to higher dimensions, but the
literature on the rami?cations of this commitment to the square
lattice for the dominant case of planar data is relatively limited.
There seems to be neither a book nor a survey paper on the subject
of alternatives. This book on hexagonal image processing is
therefore quite appropriate. Lee Middleton and Jayanthi Sivaswamy
well motivate the need for a c-
