Flynn discontinuity algorithm code
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.
