A seismic reflection study over the Bane anticline in Giles County, Virginia
… were obtained. In addition to frequency filtering, velocity filtering, and deconvolution, new methods of interpreting RMS velocity analyses were developed and applied. Persistent events at about 1.0 and 2.8 seconds were found, suggesting the presence of large reflection coefficients. On …

A signal processing approach to ultrasound localization microscopy
… as a signal processing problem and introduce a filtering operation that is capable of separating microbubble contrast agents into different subgroups based on their vector velocities while simultaneously offering blood velocity mapping at super resolution, without tracking individual …

Enhancing land seismic data with compressive sensing and processing
… enabling straightforward definitions of velocity filters that are localized in time, space, frequency and wavenumber and can therefore yield better signal and noise separation than the traditional approaches based solely on the Fourier domain.
