| Abstract: | To improve the efficiency and accuracy of the seismic structure interpretation,a method of diffusion is put forwaed to enhance the seismic image quality.The method converts the seismic data to seismic image,and then extracts structure tensor from the seismic image.With the gradient obtained by bilateral filter,the structure enhancement diffusion can preserve the orientation and magnitude of the discontinuities without needing threshold switches.The structure enhancement diffusion the allows the noise to remove and the structure to enhance cohen enhancing the discontinuity and coherency along the strata.The results applied show that the technique facilitates seismic image enhancement for structure interpretation and improves visualization of the complex tectonic style. |
