Abstract

An efficient subband image decomposition method by mathematical morphology is described in this paper, it decomposes the input signal spectrum into 4 subband images by using two separable structure elements, then each band image, can be decimated and coded effectively for data transmission. This subband pyramid scheme preserves the number of pixels as in the original image, also the data structure itself is very compact, the advantages of morphology over linear filtering approach are its direct geometric interpretations, simplicity and efficiency in implementation, some image examples are given to show the effectiveness of this approach.
