Frequency Enhancements for Visualizing 3D Seismic Data
Source: University of California
This application paper introduces a suite of enhancement techniques for visualizing seismic data. These techniques provide a better understanding of the underlying propagation process in the complex time-dependent seismic data. Traditional techniques using the accumulated displacement as a scalar or vector field for volume rendering fail to capture the dynamic frequency variations, which is essential for seismic study. The paper shows that using multiband signal filters to separate frequency components of the data can highlight different frequency bands explicitly in visualization. The end result is a combination of different displacements, such as drift and shaking along the horizontal and vertical directions which are perturbing the accumulated drifts.
