WebWe present a new method for the denoising and fusion, which is dedicated to multiazimuth seismic data. We propose to combine low-level fusion and diffusion processes through the use of a unique model based on partial differential equations. The denoising process is driven by the seismic fault preserving diffusion equation. Meanwhile, relevant information … Webusing nonlinear diffusion techniques have been proposed in the recent years ([6],[7],[8],[9],[10]). These techniques are based on the use of Partial Differential Equations (PDE). Among these diffusion based seismic denoising methods, an excellent sample is the seismic fault preserving diffusion (SFPD) proposed by Lavialle et al. [10].
