A novel localized two-dimensional (2-D) filter is proposed. The proposed filter derived from the frequency-wavenumber filter and Radon transform filter, with the filtering operation applied at the stage of Fourier projection, has good local property and less filtering distortion. An example of the proposed method to attenuate linear coherent noise in a seismic image is given. Comparisons of the results between our method and the conventional 2-D filters (including frequency-wavenumber filter and Radon transform filter) show that the new method outperforms both frequency-wavenumber method and Radon transform method
