Abstract:In this paper the designing of the Edge Preserving Smoothing(EPS) is introduced,with EPS the noise in the seismic data can be removed while the details of the seismic events can be preserved,now this method is being used in seismic data processing.EPS filter which we designed based on coherence technology and splitting and merging technology in digital image processing can work well if the seismic event in small region of 3D space can be regarded as 3D plane,with EPS the suitable filter applying time window can be founded,so the noise can be greatly reduced,better filtering results can be obtained and the fault,channel and fracture can be easily distinguished and delineated.
