Paper Abstract

In this article, we introduce a new subband structure called hybrid subband coder, which uses both linear and morphological filters at each analysis and synthesis stage. This new subband coder significantly reduces the ringing- effect distortions inherent to the linear standard coders and the smearing-effect distortions associated with the nonlinear, morphological subband coders. The performance of this new structure is compared to the linear and nonlinear subband coder results using a set of four grayscale images. The results show a modest improvement in PSNR and in visual quality.
