Detection of discontinuities in dip
WebDec 3, 2012 · The results obtained by applying this methodology to the 3D point cloud are a set of discontinuity families, characterized by their dips and dip directions, and surface wedges, essential for a later stability analysis of the jointed rock mass. We describe an strategy for automatic detection of discontinuities in jointed rock masses from a 3D … 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 …

Edge detection is the most common approach for detecting meaningful discontinuities in the gray level. …
WebUsing the TLS point cloud characterization of the rock masses it is possible to determine, apart from dip angles and Figure 1. The mouth of the tunnel studied with some rock discontinuities dip directions, other parameters such as spacing and highlighted in different colors. 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 …
WebThe three basic types of discontinuities in a digital image are point, line and edge. Point Detection: The detection of isolated point different from constant background image can be done using the following mask:-1-1-1-1: 8-1-1-1-1: ... Line Detection: The various masks present for line detection are : a) Horizontal mask-1-1-1; 2: 2: 2-1-1-1: 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.
WebWhat are edges We can also say that sudden changes of discontinuities in an image are called as edges. Significant transitions in an image are called as edges. Types of edges …
