      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, ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Designing Metrics for the Purpose of Aesthetically Evaluating 

      Greenfield, Gary R. (The Eurographics Association, 2005)
      The algorithmic and evolutionary art movements within computer-generated art have helped spur interest in evaluating images on the basis of their aesthetic merit. When attempting to use non-interactive techniques to address ...

    • Computer Generated Stereoscopic Artwork 

      Stavrakis, Stathis; Gelautz, Margrit (The Eurographics Association, 2005)
      The focus of this work is to investigate and simulate artistic techniques in stereoscopy that go beyond stereo photography, such as stereoscopic painting. We briefly discuss the topic from a stereo artist s perspective and ...

    • Color Search and Replace 

      Grundland, Mark; Dodgson, Neil A. (The Eurographics Association, 2005)
      We present an interactive image enhancement technique to adjust the global color composition of an image by finding and replacing color gradients. We show how color gradient transformations can perform the basic operations ...

    • 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 ...

    • 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 ...

    • Aesthetics in Covariant Image Reconstruction 

      Georgiev, Todor (The Eurographics Association, 2005)
      This paper describes a method of seamless cloning based on aesthetic theory of lightness perception. Judgment of lightness and color harmony is treated as low level aesthetic judgment made by the human visual system. The ...

    • A Palette-Driven Approach to Image Color Transfer 

      Greenfield, Gary R.; House, Donald H. (The Eurographics Association, 2005)
      Color analysis of images for the purpose of color balancing, color contrast, and color correction is critical in image processing applications. Color analysis of images for the purpose of palette extraction has received ...

    • Enhancing Perceived Depth in Images Via Artistic Matting 

      Gooch, Amy A.; Gooch, Bruce (The Eurographics Association, 2005)
      We present an algorithm for the addition of artistic mattes to digital images for the purpose of enhancing the sense of depth in the image. We provide examples exploring color and double mattes as well as report the results ...

    • 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 ...

    • 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 ...

    • Illustrative Scientific Visualization Framework 

      Sousa, Mario Costa; Gooch, Amy Ashurst; Gooch, Bruce (The Eurographics Association, 2005)
      Current scientific visualization techniques create complex images that may be difficult to interpret and do not have the expressiveness of illustrations. Incorporating traditional scientific illustration techniques into a ...

    • A Generative Model For Dynamic Canvas Motion 

      Kaplan, Matthew; Cohen, Elaine (The Eurographics Association, 2005)
