  • The DSO Feature Based Point Cloud Simplification

    Publication Year: 2011, Page(s):1 - 6
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (364 KB) | HTML iconHTML

    This study proposes an effective low-error point cloud simplification method to retain the physical features of the models. The value of Discrete Shape Operator (DSO) is adopted to extract the features points of the models, and those are postponed to simplify. The value of DSO is defined as the discrete sum over the directional curvature and torsion. The proposed method improves the Quadric Error ... View full abstract»

  • Stabilizing Marker-Based Visual Tracking Using Markers with Scattering Materials and Multiple Cameras

    Publication Year: 2011, Page(s):7 - 12
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (478 KB) | HTML iconHTML

    The marker-based method in visual tracking is generally convenient, while the stability of the position and orientation estimation of the camera depends on the illumination conditions because it is processed on the basis of the camera images. However, illumination conditions are often difficult to control in practical environments. Although some solutions have been proposed for illumination change... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (728 KB) | HTML iconHTML

    The imaging system normally used and the reproduction media has the capability to perceive scenes within a narrow range of contrast whereas the human visual system can perceive very high contrast with ease. We constantly strive to map one such set of colors to another or to address the problem of strong contrast reduction from active values to the displayable range preserving the image details. Th...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (387 KB) | HTML iconHTML

    The aim of this research is to create a production model for interactive art in a narrative form. We establish a conceptual framework for the development of a narrative in terms of its interactive scenario, graphic design, and technical design. Based on this framework, we create a prototype of a "Magic Monkey, " which is interactive art in a narrative form. We exhibit a prototype of "Magic Monkey"... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1102 KB) | HTML iconHTML

    A positive rational cubic function [8] has been extended to positive rational bi-cubic partially blended function to visualize the shape of 3D positive data. To preserve the shape of positive data, simple data dependent constraints are derived on the free parameters in the description of rational bi-cubic partially blended functions. The developed scheme is local and C1. View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1390 KB) | HTML iconHTML

    Modeling Bezier surface at high degree is expensive in terms of computational time due to an excessive number of control points. This is a well-known major problem in Bézier surface construction. To significantly solve this problem, a new algorithm that can reduce computational time while remain a highly accurate result, is introduced by utilizing a simple equation to increase the number o...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1001 KB) | HTML iconHTML

    In this paper we address the problem of geometric data fitting of ordered data points, considering the case where the system is much less powerful than the modern personal computers, as in real time systems. Our method achieves timing results around 70 mS for 189 data points and requires very little effort from the system. The proposed method can be summarized in the following three steps: first, ...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (320 KB) | HTML iconHTML

    In this paper, we explore a novel and straightforward solution for manipulating the middle weights of Conic Splines. Proposed method is based on novel types of weight points which are introduced here for the first time. Using these weight points, each Conic Spline is divided into two lines and a curve. Then, weight points are placed on the junction points of the lines and curve. After setting the ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (477 KB) | HTML iconHTML

    3D scanned technology has found its increasing application in computer animated movie and game. Due to the over density of scanned data, simplification becomes a crucial process. Many researches have been done in mesh-based (i.e. triangulated faces) simplifications. However, few are focused on preserving the completeness of skeleton semantic. And in sharply simplification case, the losing of skele... View full abstract»
