  • Toward a Perceptual Theory of Flow Visualization

    Currently, most researchers in visualization pay very little attention to vision science. The exception is when the effective use of color is the subject. Little research in flow visualization includes a discussion of the related perceptual theory. Nor does it include an evaluation of effectiveness of the display techniques that are generated. This is so, despite Laidlaw's paper showing that such ... View full abstract»

    In this article, we report on the contest's data set and tasks, the judging criteria, the winning tools, and the overall lessons learned in the competition. We believe that by organizing these contests, we're creating useful resources for researchers and are beginning to understand how to better evaluate VA tools. Competitions encourage the community to work on difficult problems, improve their to... View full abstract»

  • Informational Aesthetics Measures

    The Birkhoff aesthetic measure of an object is the ratio between order and complexity. Informational aesthetics describes the interpretation of this measure from an information-theoretic perspective. From these ideas, the authors define a set of ratios based on information theory and Kolmogorov complexity that can help to quantify the aesthetic experience. View full abstract»

    In this article, we adopt Jin et al.'s GPU-based method to solve the Navier-Stokes equations and model the fluid evolution of the patterning process. Based on this method, we add more flexible dye injection operations and more locally controllable pattern design tools. We based our nondissipative solver on semi-Lagrangian methodology, which eliminates the blur artifacts while keeping the performan... View full abstract»

  • Viewpoint-Based Ambient Occlusion

    We've developed a new ambient occlusion technique based on an information-theoretic framework. Essentially, our method computes a weighted visibility from each object polygon to all viewpoints; we then use these visibility values to obtain the information associated with each polygon. So, just as a viewpoint has information about the model's polygons, the polygons gather information on the viewpoi... View full abstract»

  • Automatic Mood-Transferring between Color Images

    This paper presents a new color-conversion method that offers users an intuitive, one-click interface for style conversion. So, rather than having to supply a reference image, users simply select a color mood with a mouse click. To address the color-transfer quality problem, we associate each color mood with a set of up to 10 images from our image database. After selecting their color mood, users ... View full abstract»

  • Measuring Stipple Aesthetics in Hand-Drawn and Computer-Generated Images

    Publication Year: 2008, Page(s):62 - 74
    Cited by:  Papers (11)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4106 KB) | HTML iconHTML

    When people compare a computer-generated illustration to a hand-drawn illustration of the same object, they usually perceive differences. This seems to indicate that the two kinds of images follow different aesthetic principles. To explore and explain these differences, the authors compare texture stippling in hand-drawn and computer-generated illustrations, using image-processing analysis techniq... View full abstract»

  • Representing Rotations and Orientations in Geometric Computing

    This article provides a useful perspective of understanding, representing, and manipulating 3D orientation and rotation for geometric computing. Coordinate-free geometric programming and affine geometry, which makes a distinction between points and vectors and defines operations for combining them, inspires our approach. Based upon affine geometry, Goldman and DeRose pioneered a method of writing ... View full abstract»

  • Automatic High-Dynamic Range Image Generation for Dynamic Scenes

    Automatic high-dynamic range image generation from low- dynamic range images offers a solution to conventional methods, which require a static scene. The method consists of two modules: a camera-alignment module and a movement detector, which removes the ghosting effects in the HDRI created by moving objects. View full abstract»

    The future standards for immersive VR workshop at the IEEE Virtual Reality 2007 Conference aimed to foster an understanding between the VR and Web3D communities. Although the fields of VR and Web-based 3D graphics tend to view their technologies as different beasts, the technologies share many requirements regarding virtual world content: modeling, lighting, animation, interaction, and direct mani...

    Future innovations in computing technologies are just as likely to be driven by the outside demands for these technologies than by improvements driven from within the computer science community. In this regard, I define "computing" as the union of concerns including traditional computer science (such as systems, architecture, networking), human-computer interaction (HCI), graphics and animation, r...
