A boostlet transform for wave-based acoustic signal processing in space-time
Elias Zea, Marco Laudato, Joakim Andén
Sparse representation systems that encode signal architecture have had a profound impact on sampling and compression paradigms. Remarkable examples are multi-scale directional syst…

Sparse wavefield reconstruction and denoising with boostlets
Elias Zea, Marco Laudato, Joakim Andén
Boostlets are spatiotemporal functions that decompose nondispersive wavefields into a collection of localized waveforms parametrized by dilations, hyperbolic rotations, and transla…
