BEMD and assisted knowledge based meteorological facsimile map enhancement

An enhancement algorithm for weather fax map with zero-mean Gaussian noise is proposed based on BEMD and self features of meteorological facsimile maps. First decompose the noised meteorological facsimile map to IMF 1 and a residue, then estimate the variance of the noise via BEMD and IMF 1 through...
