A Classification of Continuous Wavelet Transforms in Dimension Three
This paper presents a full catalogue, up to conjugacy and subgroups of finite index, of all matrix groups H < GL(3,ℝ) that give rise to a continuous wavelet transform with associated irreducible quasi-regular representation. For each group in this class, coorbit theory allows to consistently define spaces of sparse signals, and to construct atomic decompositions converging simultaneously in a whole range of these spaces. As an application of the classification, we investigate the existence of compactly supported admissible vectors and atoms for the groups.
