WebABSTRACT. The local orthogonalization (LO) approach has been broadly applied to attenuate random noise and deal with the signal-leakage problem induced using the traditional denoising schemes. First, this approach removes noise and applies the LO weight (LOW) operator to the originally estimated signal. Then, the signal leakage is … WebABSTRACT We have developed a method for suppressing coherent noise from seismic data by using the morphological differences between the noise and the signal. This method consists of three steps: First, we applied a dictionary learning method on the data to extract a redundant dictionary in which the morphological diversity of the data is stored. Such a … avantis japan
