Unsupervised Seismic Wave Separation in the Time/Scale Plane

P161 UNSUPERVISED SEISMIC WAVE SEPARATION IN THE TIME/SCALE PLANE Abstract This paper illustrates a methodology based on an image processing technique to remove and separate surface waves. These waves convey any useful information despite the shot and receivers sensors patterns used during the data acquisition. The elimination of such waves is always desirable to focus on underlying reflection data. Methods based on time frequency and time scale methods are now used to separate surfaces waves. But they are not so convenient because they are not automatic. The proposed method based on the watershed algorithm is an unsupervised and non parametric
