Abstract :
As bridge technology in the study of the Bidimensional Empirical Mode Decomposition (BEMD) application, this paper gives an integrated anlysis of the Intrinsic Mode Function (IMF) image characters including energy characters, amplitude&frequency characters and phase&frequency characters . Some important conclusions are drawned that the main part energy of the original image´s frequency amplitude remains in the residue and most part of the fourier phase information of the original image is herited by IMF1. To calculate the relationship between the IMF image information and the origianal image information, this paper brought out the concept of Mode Fourier Phase Inheritage Rate (MFPIR), calculated the referent data that the IMF1 image carry more than 90% original image information, and also veriphied the advantages of the novel stopping criterion.
