ABSTRACT

Local slope is an of import attribute that can aid distinguish seismic signals from dissonance. Based on optimal slope estimation, many filtering methods can be designed to enhance the signal-to-noise ratio of noisy seismic data. Nosotros present an open up-source MATLAB lawmaking package for local gradient estimation and corresponding structural filtering. This package includes 2D and 3D examples with ii main executable scripts and related subfunctions. All lawmaking files are in the MATLAB format. In each main script, local slope is estimated based on the well-known aeroplane-wave destruction algorithm. And then, the seismic information are transformed to the flattened domain by utilizing this slope data. Furthermore, the smoothing operator can be effectively applied in the flattened domain. We introduce the theory and mathematics related to these programs and nowadays the constructed and field data examples to show the usefulness of this open up-source package. The results of local slope estimation and structural filtering demonstrate that this package can be conveniently and finer practical to the seismic signal analysis and denoising.
