In mathematics, the structure tensor, also referred to as the second-moment matrix, is a matrix derived from the gradient of a function. It describes the distribution of the gradient in a specified neighborhood around a point and makes the information invariant respect the observing coordinates. The structure tensor is often used in image processing and computer vision. WebThe iconic coherence attribute is very useful for geologic feature imaging such as faults, deltas, submarine canyons, karst collapse, mass transport complexes, and more. Besides its preconditioning, the interpretation of discrete stratigraphic features on seismic data is also limited ... • Gradient structure tensor-based (Bakker, 2003 ...

The only way to change a coherence is to apply a pulse by phase ϕ. Therefore, we must know the coherence pathway we are interested in and we need to set the phases of the pulses and receiver accordingly.

WebPulsed field gradients (PFGs), also known as gradient enhanced spectroscopy (GES), can be used to achieve coherence selection and minimize the need for extensive phase cycling. In PFG spectroscopy a large z -gradient is introduced along the sample's vertical axis (magnitude approximately 0.1–0.5 T m −1 and duration approximately 1 ms ...
