Method and apparatus for filtering irregularly sampled data

摘要

A method and apparatus for filtering data acquired at a plurality of discrete data points is described, using the steps of defining a filter having defined filter values at defined filter points at least partially not coincident with the data points and using the defined filter values at the defined filter points to determine filter values at the data points, thereby correcting the filter to have filter values at filter points coinciding with the data points and filtering the data using the corrected filter. The method and apparatus specifically relates to a process for multi-dimensional filtering of irregularly sampled seismic data.
