This contributed quantity explores the relationship among the theoretical features of harmonic research and the development of complex multiscale representations that experience emerged in sign and photograph processing. It highlights probably the most promising mathematical advancements in harmonic research within the final decade led to via the interaction between diverse components of summary and utilized arithmetic. This intertwining of rules is taken into account ranging from the speculation of unitary team representations and resulting in the development of very effective schemes for the research of multidimensional data.
After an introductory bankruptcy surveying the medical importance of classical and extra complex multiscale equipment, chapters hide such themes as
- An assessment of Lie concept fascinated about universal functions in sign research, together with the wavelet illustration of the affine workforce, the Schrödinger illustration of the Heisenberg workforce, and the metaplectic illustration of the symplectic group
- An creation to coorbit thought and the way it may be mixed with the shearlet remodel to set up shearlet coorbit spaces
- Microlocal homes of the shearlet remodel and its skill to supply an actual geometric characterization of edges and interface obstacles in photos and different multidimensional data
- Mathematical suggestions to build optimum facts representations for a couple of sign kinds, with a spotlight at the optimum approximation of services ruled through anisotropic singularities.
A unified notation is used throughout all the chapters to make sure consistency of the mathematical fabric presented.
Harmonic and utilized research: From teams to indications is aimed toward graduate scholars and researchers within the parts of harmonic research and utilized arithmetic, in addition to at different utilized scientists attracted to representations of multidimensional info. it might probably even be used as a textbook
for graduate classes in utilized harmonic analysis.
