Flynn discontinuity algorithm code
WebDec 23, 2024 · Segmentation. Segmentation is the separation of one or more regions or objects in an image based on a discontinuity or a similarity criterion. A region in an image can be defined by its border (edge) or its interior, and the two representations are equal. There are prominently three methods of performing segmentation: WebFlynn's minimum discontinuity phase unwrapping is one of the algorithm which can solve many different kinds of phase unwrapping problems successfully, but its computation efficiency is too low. To overcome this drawback, a blocked minimum …

Since the unwrap function applies to column wise, and for cases with angles (other than 0) the discontinuity appears in gamma degrees (so for 30, it would … 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.
