Abstract

We present an algorithm for compression of greyscale images, which is a modification of the morphological sub-band decomposition algorithm proposed by Pei and Chen. In the first step, an input image is decomposed into four sub-bands using morphological opening and closing filters. In the second step, sub-bands are compressed with lossless methods matched to the dynamics of each sub-band. After transmission the sub-bands are decompressed and added together to form the output image. Results of computer simulations are presented.
