Local Angle Extraction and Noise Attenuation for Seismic Image Using Contourlet Transform

Abstract

We propose contourlet-based algorithms to extract local angle from seismic migrated images and attenuate seismic noise. Steerable pyramid and projection-filter-based complex wavelet transform have been used to extract seismic local angle, while curvelet transform and complex wavelet transform have been used to attenuate seismic noise. However, previously… (More)
