SUBBAND CODING OF IMAGES: NOVEL APPROACHES AND SOME IMPROVEMENTS

Miodrag Popović and Dragutin Šević

The novel approaches and some computational improvements of subband coding of images are described in this paper. Special attention is given to: 2times1-D and nonseparable 2-D wavelet decompositions, computationally improved 2-D ELT and fuzzy postprocessing of subband coded reconstructions. A common characteristic of presented case studies is that the problem of image coding is conceptually treated as a two-dimensional one, although separability is largely exploited for efficiency purposes. Some experimental results of simulations of subband coding of images using different algorithms are also presented.
