A contour-texture approach to picture coding

A new image coding technique, based on a simplified description of a region-composed image is presented. The regions are extracted from the original image by an adaptive psychovisually oriented segmentation process. The picture elements (pels) inside the regions represent the texture information of the image whereas the region boundaries points represent the contour information. The data-adaptive character of this method as well as the use of some psychovisual characteristics of the human visual system lead to promising results in data compression.
