Abstract We propose an expected patch log likelihood (EPLL) based denoising method for nonstationary seismic random noise which has spatiotemporally varying variance, by incorporating the patch classification and mixed Gaussian mixture model (GMM), named PC-EPLL. In this method, the overlapping pat...
