Comparison of two interpolative coding methods: DIDT and RBN

This paper compares two coding methods that differs in segmentation and reconstruction strategy, but they both use interpolation as basic reconstructor. The general scheme is given in fig.1 . First the picture is segmented and the relevant information of each segment is extracted, secondly this information is coded and this information is used for the reconstruction of the picture. A brief description of the segmentation methods is given in part 2. For a more detailed description see [VAN]. The relation between segmentation and reconstruction is also described. In part 3 and 4 the reconstruction strategies for DIDT and RBN are treated in detail. The last part will compare some results of simulations on real images.
