WebThe result of the algorithm in Figure 3(c) is composed of a two-planar surface tearing along the median shear line as expected, except for some protrusions on this line where the phases are severely corrupted by both the noise and the object discontinuities. The conventional minimum -norm method offers a slightly worse result, shown in Figure 3(d), … WebDiscontinuity attributes are a variety of post-stack calculations that measure the degree of local similarity or dis-similarity between seismic traces. Discontinuities in a seismic volume, such as faults or mass transport deposits, are apparent as regions of low similarity.
