Orthogonal and Biorthogonal FIR Hexagonal Filter Banks With Sixfold Symmetry
Recently hexagonal image processing has attracted attention. The hexagonal lattice has several advantages in comparison with the rectangular lattice, the conventionally used lattic...

On well-rounded sublattices of the hexagonal lattice
Abstract. We produce an explicit parameterization of well-rounded sublattices of the hexagonal lattice in the plane, splitting them into similarity classes. We use this parameteriz...

H2O: Reversible Hexagonal-Orthogonal Grid Conversion by 1-D Filtering
In this work, we propose a new grid conversion algorithm between the hexagonal lattice and the orthogonal (a.k.a. Cartesian) lattice. The conversion process, named H2O, is easy to...

New optimized spline functions for interpolation on the hexagonal lattice
We propose new discrete-to-continuous interpolation models for hexagonally sampled data, that generalize two families of splines developed in the literature for the hexagonal latt...
