WebNov 1, 2014 · Robust discontinuity detection using Eq. (1) or Eq. (5) relies on the assumption that the input seismic amplitude should vary with zero mean. However, when the features of interest fail to be of zero mean, both equations provide an underestimate of the discontinuity attribute and such estimates would decrease the lateral resolution on … WebDetection of Discontinuities: There are 3 basic types of discontinuities: points, lines and edges. The detection is based on convoluting the image with a spatial mas. Point detection. A point has been detected at the location p(i,j) on which the mask is centered if R >T, where T is a nonnegative threshold, and R is obtained with the following ...

WebOct 17, 2024 · In this context, a steering dataset was generated, and a dip-steered median filter (DSMF), a dip-steered diffusion filter, and a fault enhancement filter (FEF) were applied to sharpen the discontinuities. Structural attributes were evaluated, to investigate how the newly applied data conditioning affects the clarity of fault patterns.
