An image compression method based on the multi-resolution characteristics of BEMD

This paper presents a BEMD based image compression method based on the multi-resolution characteristics of BIMF. First, an image pyramid of an original image is formed by the down-sampling technique, and then a cascade feedback compression framework is constructed based on the spatial similarity property of the BIMFs at different resolutions. The image compression scheme is implemented by coding the decomposition result at the lowest resolution level. Experimental results show the effectiveness of the proposed method.
