Detection of discontinuities in dip

WebEdge detection refers to the process of identifying and locating sharp discontinuities in an image. The discontinuities are abrupt changes in pixel intensity which characterize boundaries of objects in a scene. Edge detection refers to the process of extracting edges from the image where there are sudden changes or discontinuities. WebTo detect discontinuities, manual plane segmentations are done on the former product (Feng and Röshoff 2004;Haneberg 2008), while automatic/semi-automatic extraction is …
