3D Edge Preserving Smoothing andApplications

摘要

This paper presents a new algorithm for reducing noise in seismic impedance cubes whilepreserving structural and stratigraphic discontinuities or edges. The method divides a moving3D cubicle, surrounding every location in the impedance cube, into number of segments. Theaverage values of the most homogenous segment will be assigned as the output at the centrallocations of the cubicles. The main advantage of this 3D edge preserving smoothing (EPS)algorithm is that it can preserve not only spatial but also vertical edges (e.g., the impedanceboundaries). No dip steering is needed as usually required for smoothing seismic amplitudedata.
