The first case depicts the original data where trace segments are aligned horizontally whereas the second case shows the effects of the applied full steering attribute, the location and azimuth of the traces are being updated at each trace location.
3D image of the principle of dip-steering attributes estimation is presented in Fig. 5; the arrows are pointing in various steering directions.
Other applications of dip-steering attributes include the estimation of some unique attributes such as dip and azimuth, 3D curvature and dip variance.
The dip-steering attribute analysis allows the creation of steering cube that contains both local dip and azimuth positions at each sample position.

Interestingly, Zakis et al. found several large asymmetries between trained left and right steering coefficients, which they attribute to symmetric gain adjustments with highly asymmetric SPL estimates.
We did not include death among the events to be assessed since the steering committee decided to attribute it automatically the worse rating (i.e., 10).
As features, principal components of combination of attributes such as steering angle, speed, longitudinal acceleration, lateral acceleration, and yaw rate were used.
He also attributed their sluggish steering under sail to interference with the flow of water to the rudder by the fixed propeller.
This effect is jointly attributed to the steering apodisation of the phased array and to the tissue-specific variable response (e.g., variable shadowing of the ribs at different foci).
A steering cube designed using dip-steered median filter attribute can be used to effectively perform a structurally oriented filtering.
