We describe a new computational approach to stylize the colors of an image by using a reference image. During processing, we take characteristics of human color perception into account to generate more appealing results. Our system starts by classifying each pixel value into one of a set of the basic color categories, derived from our psycho-physiological experiments. The basic color categories are perceptual categories that are universal to everyone, regardless of nationality or cultural background. These categories provide restrictions on the color transformations to avoid generating unnatural results. Our system then renders a new image by transferring colors from a reference image to the input image, based on this categorizations. To avoid artifacts due to the explicit clustering, our system defines fuzzy categorization when pseudo-contours appear in the resulting image. We present a variety of results and show that our color transformation performs a large, yet natural color transformation without any sense of incongruity, and that the resulting images automatically capture the characteristics of the color use of the reference image.

The range of issues considered in graph drawing includes algorithms, graph theory, geometry, topology, order theory, graphic languages, perception, app- cations, and practical systems. Much research is motivated by applications to systems for viewing and interacting with graphs. The interaction between th- retical advances and implemented solutions is an important part of the graph drawing eld. The annually organized graph drawing symposium is a forum for researchers, practitioners, developers, and users working on all aspects of graph visualization and representations. The preceding symposia were held in M- treal (GD’98), Rome (GD’97), Berkeley (GD’96), Passau (GD’95), Princeton (GD’94), and Paris (GD’93). The Seventh International symposium on Graph Drawing GD’99 was or- nized at Sti r n Castle, in the vicinity of Prague, Czech Republic. This baroque castle recently restored as a hotel and conference center provided a secluded place for the participants, who made good use of the working atmosphere of the conference. In total the symposium had 83 registered participants from 16 countries.
