Intrepid Filtering supports spatial and spectral domain filters (and their combination) on line and gridded datasets to enhance geophysical data and features.
GridFFT is the primary grid filtering tool from Intrepid, it can be used to enhance or correct features, remove noise or transform the signal data. The tool conducts the enhancements by converting data into Fourier space and back once complete. A range of predefined filters can be used in isolation, or in combination to enhance your data. Intrepid also has two other grid filtering tools, Spatial Convolution and Wiener Kernels.
