<p>Methods and devices for seismic data processing attenuate noise by replacing an attribute value v(i) of a selected data point i with a weighted average f2(i) of attribute values of data points from a window that includes the selected data point i. The contribution to the weighted average of an attribute value vj) corresponding to a data point j depends on how similar attribute values in the neighborhood N of the data point j are to attribute values in the neighborhood N; of the selected data point i. Figure 6 600 Start Selecting a data point i in the seismic data cube, wherein the data point i is associated with an attribute value v(i) Choosing a window W. that includes the data point i -630 Replacing the attribute value v(i) with a weighted average V(1) calculated based on attribute values vj) of data points j within the window W.
