In this article we present an approach to compression of segmented images using wavelet transform. The original image is segmented using an unsupervised regions segmentation method. The segments are approximated using polygons to minimise the representation. For texture approximation we use iterated wavelet orthogonal transform. We develop a new scheme for approximation and coding which optimises the results in rate-distortions sense. Proposed scheme gives comparative results to T. Karlubikova et al. (2002) but with significant speed-up of computation.
