Taking signal and noise to new dimensions

The inherent complexity of seismic data has sparked, since about half a century, the development of innovative techniques to separate signal and noise. Localized time-scale representations (e. g. wavelets), parsimonious deconvolution, sparsity-promoted restoration and reconstruction are now at the core of modern signal processing and image analysis algorithms. Together with advances from computer science and machine learning, they shaped the field of data science, aiming at retrieving the inside structure of feature-rich, complex and high-dimensional datasets. This special issue is devoted to novel methodologies and strategies capable of tackling the large data volumes necessary to harness the future of subsurface exploration. A common trait resides in the possibility to seize at the same time both signal and noise properties along lower dimensional spaces, with dedicated metrics, to allow their joint use for seismic information enhancement. The traditional frontier between signal and noise is dimming, as incoherent seismic perturbations and formerly detrimental coherent wavefields, such as multiple reflections, are nowadays recognized as additional information for seismic processing, imaging and interpretation. We welcome contribution pertaining (but not limited) to:
  • emerging seismic data acquisition and management technologies
  • more compact, sparser and optimized multidimensional seismic data representations
  • filtering, noise attenuation, signal enhancement and source separation
  • advanced optimization methods and related metrics, regularizations and penalizations
  • artificial intelligence and machine learning applications for seismic data characterization
  • novel applications of signal and image processing to geophysics
  • hardware and software algorithmic breakthroughs
