    • A Generative Model For Dynamic Canvas Motion 

      Kaplan, Matthew; Cohen, Elaine (The Eurographics Association, 2005)
      We present techniques for constructing realistic canvas and paper models and for enabling interactive dynamic canvas motion. Dynamic canvas motion means that there is a correspondence between the motion of canvas features ...
    • Straight away on Curved Spaces 

      Marty, Alain (The Eurographics Association, 2005)
      Two points of a Euclidean space can always be connected by the simplest of the curves, the straight line. This curve is unique (it s required), with a constant direction and a minimal length between the two points. The ...
    • Sketch Based Construction and Rendering of Implicit Models 

      Wyvill, Brian; Foster, Kevin; Jepp, Pauline; Schmidt, Ryan; Sousa, Mario Costa; Jorge, Joaquim A. (The Eurographics Association, 2005)
      We present an implicit modeling system as a tool for creating a wide range of aesthetic models. Because of their ability to form blends and produce both organic shapes as well as man-made objects, implicit surfaces are a ...
    • Color Style Transfer Techniques using Hue, Lightness and Saturation Histogram Matching 

      Neumann, Attila; Neumann, László (The Eurographics Association, 2005)
      We present new methods which transfer the color style of a source image into an arbitrary given target image having a different 3D color distribution. The color transfer has a high importance ensuring a wide area of ...
    • Illustrative Visualization for Medical Training 

      Sousa, Mario Costa; Ebert, David S.; Stredney, Don; Svakhine, Nikolai A. (The Eurographics Association, 2005)
      A system is presented that produces images that simulate pictorial representations for both scientific and biomedical visualization. It combines traditional and novel volume illustration techniques. We present examples to ...
    • Form Follows Function: Aesthetic Interactive Labels 

      Götzelmann, Timo; Ali, Kamran; Hartmann, Knut; Strothotte, Thomas (The Eurographics Association, 2005)
      Labels effectively convey co-referential relations between textual and visual elements and are a powerful tool to support learning tasks. Therefore, almost all illustrations in scientific or technical documents employ a ...
    • An Information-Theoretic Framework for Image Complexity 

      Rigau, Jaume; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2005)
      In this paper, we introduce a new information-theoretic approach to study the complexity of an image. The new framework we present here is based on considering the information channel that goes from the histogram to the ...
    • Global Contrast Factor - a New Approach to Image Contrast 

      Matkovic, Kresimir; Neumann, László; Neumann, Attila; Psik, Thomas; Purgathofer, Werner (The Eurographics Association, 2005)
      Contrast in image processing is usually defined as a ratio between the darkest and the brightest spots of an image. In this paper we introduce a different contrast definition. The newly introduced Global Contrast Factor ...
    • Viewpoint Quality: Measures and Applications 

      Sbert, Mateu; Plemenos, Dimitri; Feixas, Miquel; González, Francisco (The Eurographics Association, 2005)
      Several methods that use the notion of viewpoint quality have been recently introduced in different areas of computer graphics, such as scene understanding, exploration of virtual worlds, radiosity and global illumination, ...
    • Computer Aided Color Appearance Design using Environment Map Based Lighting 

      Shimizu, Clement; Meyer, Gary W. (The Eurographics Association, 2005)
      A BRDF approximation is developed that is suitable for interactive color appearance design in direct lighting provided by environment maps. The BRDFs are approximated as a linear combination of cosine lobes with a fixed ...
    • Computational Color Harmony based on Coloroid System 

      Neumann, László; Nemcsics, Antal; Neumann, Attila (The Eurographics Association, 2005)
      This paper presents experimentally based rules and methods for the creation of harmonic color sets. First, dichromatic rules are presented which concern the harmony relationships of two hues. For an arbitrarily given hue ...
    • Smart Visibility in Visualization 

      Viola, Ivan; Gröller, Eduard (The Eurographics Association, 2005)
      In this paper we discuss expressive visualization techniques that smartly uncover the most important information in order to maximize the visual information in the resulting images. This is achieved through dynamic changes ...
    • Computational Automotive Color Appearance 

      Meyer, Gary W.; Shimizu, Clement (The Eurographics Association, 2005)
      A computer graphic system has been developed that permits the interactive design of new automotive finishes. The software makes use of a reflection model for car paint that is based on industry standards for measuring the ...
    • Abstraction and Depiction of Sparsely Scanned Outdoor Environments 

      Xu, Hui; Gossett, Nathan; Chen, Baoquan (The Eurographics Association, 2005)
      This paper describes various techniques and applications of rendering three-dimensionally digitized outdoor en- vironments in non-photorealistic rendering styles. The difficulty in rendering outdoor environments is ...
    • On Nonlinear Perspectives in Science, Art and Nature 

      Glaeser, Georg (The Eurographics Association, 2005)
      Classic perspectives, i.e., central projections onto a plane, are extremely common in our days. Photos, movies, computer generated animations almost exclusively use this technique. They are linear since straight lines in ...
    • Breaking the Pixel Barrier 

      Isenberg, Tobias; Carpendale, M. Sheelagh T.; Sousa, Mario Costa (The Eurographics Association, 2005)
      The majority of the current advances in computer graphic rendering strive for fast and realistic creation of pixel images, e. g., for the film and gaming industry. This development, unfortunately, leads to various problems ...
    • Benford's Law for Natural and Synthetic Images 

      Acebo, Esteve Del; Sbert, Mateu (The Eurographics Association, 2005)
      Benford's Law (also known as the First Digit Law) is well known in statistics of natural phenomena. It states that, when dealing with quantities obtained from Nature, the frequency of appearance of each digit in the first ...
    • Aesthetics in Covariant Image Reconstruction 

      Georgiev, Todor (The Eurographics Association, 2005)
