We propose a pre-processing step based on a non-linear diffusion filtering leading to a better detection of seismic faults. WebThe denoising process is driven by the seismic fault preserving diffusion equation. Meanwhile, relevant information (as seismic faults) is injected in the fused 3-D images by an inverse diffusion process. One of the advantages of such an original approach is to improve the quality of the results in case of noisy inputs, which are frequently ...
