According to the system intrinsic quality of self-comparability and the empirical mode decomposition algorithm of
completeness and stability, an improvement algorithm for EMD image decomposition is presented. It is integrity, fast
and effective. Some aspects were improved that bidimensional interpolation methods and end conditions of getting
intrinsic mode image. Three questions of general algorithm for EMD image decomposition were solved. First, the
algorithm for image decomposition was slow; Second, some points were not contained because of delaunay triangulation;
Third, the end condition of algorithm was not accuracy. Experiments were made by Matlab and the validity of the
improvement algorithm was validated.
