Wavelet analysis provides a framework for decomposing signals and functions into basis elements that are localised in both time (or space) and frequency. Central to this approach is the concept of ...

Frame theory generalises the concept of an orthonormal basis by allowing redundant, yet stable, expansions of vectors in a Hilbert space. Rather than seeking a unique representation, frames permit ...

In an increasingly data-driven world, mathematical tools known as wavelets have become an indispensable way to analyze and understand information. Many researchers receive their data in the form of ...
