<p>A method can include accessing seismic data; providing a wave function that defines, at least in part, a correlation window length; generating local 5 autocorrelation functions for the seismic data using the correlation window length; performing cross-correlations between the wave function and each of the local autocorrelation functions to provide local cross correlation coefficient values; determining second 10 derivatives of the local cross-correlation coefficient values to provide local second derivative values; and rendering the local second derivative values to a display. Various other apparatuses, systems, methods, etc., are also disclosed. 3270609_1 (GHMatters) P90082.AU 3/04/12 Access Seismic Data 411, Provide Wave Function (e.g., a cosine function) rCRM Generate Local Autocorrelation Functions Perform Cross-Correlations of Functions (e.g., correlation-cosine transform) Determine Second Derivatives Render Displayable Result Fig. 4</p> |
