Indeed we present numerical algorithms for the (exact) evaluation, interpolation, and approximation of . functions on finite sets of spatial samples ., invariant under the action of ..

Meshfree Methods Based on Global Weak-Forms,complete for regular cyclic lifts but not for left-invariant ones. This yields us to consider stronger invariants, the . and . invariants. We then prove the main theorem of the chapter: Theorem ., which states that, up to a centering operator, these invariants are weakly complete on left-invariant l

We also present how this structure can be exploited for image reconstruction and then introduce our novel framework for texture analsysis and pattern recognition, via the bispectrum. We end the chapter with a discussion on the organization of the monograph.

This apparently very simple group is in fact quite atypical: it is maximally almost periodic, which leads to much simpler harmonic analysis compared to .SE(2).. Based upon this semi-discrete model, the authors improve on previous image-reconstruction algori
