Extracting details from images based on 1-DEMD

A new algorithm based on the 1-Dimensional Empirical Mode Decomposition(1-DEMD) is developed to extract details from 2-dimensional images.First,the 2-dimensional image matrices must be previously transformed into 1-D image vectors according to the line or column of the image matrix;then the 1-DEMD can be used for decomposition.In order to achieve both vertical and horizontal details of the image,matrix-to-vector transform according to the line or column of the image matrix is cross-used by 1-DEMD.Experimental results validate the feasibility of the proposed method.
