    • OaIF: Occlusion‐Aware Implicit Function for Clothed Human Re‐construction 

      Tan, Yudi; Guan, Boliang; Zhou, Fan; Su, Zhuo (© 2023 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2023)
      Clothed human re‐construction from a monocular image is challenging due to occlusion, depth‐ambiguity and variations of body poses. Recently, shape representation based on an implicit function, compared to explicit ...

    • Object Calibration for Augmented Reality 

      Whitaker, Ross T.; Crampton, Chris; Breen, David E.; Tuceryan, Mihran; Rose, Eric (Blackwell Science Ltd and the Eurographics Association, 1995)
      Augmented reality involves the use of models and their associated renderings to supplement information in a real scene. In order for this information to be relevant or meaningful, the models must be positioned and displayed ...

    • An Object Model for Multimedia Programming 

      Arbab, F.; Herman, I.; Reynolds, G.J. (Blackwell Science Ltd and the Eurographics Association, 1993)
      The development of multimedia applications is a complex task. Much of this complexity stems from requirements associated with programming multiple media objects and the control of dependences and inter-relationships between ...

    • AN OBJECT ORIENTED APPROACH TO ENSURE PORTABILITY OF CAD STANDARD PARTS LIBRARIES 

      Pierra, Guy (Eurographics Association, 1990)
      The integration, in CAD systems, of libraries of standard parts is often considered to be one of the key factors for increasing productivity of Computer Aided Design [1] [2] [3]. These libraries must be able to integrate ...

    • Object Partitioning for Support-Free 3D-Printing 

      Karasik, Eli; Fattal, Raanan; Werman, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Fused deposition modeling based 3D-printing is becoming increasingly popular due to it's low-cost and simple operation and maintenance. While it produces rugged prints made from a wide range of materials, it suffers from ...

    • Object Repositioning Based on the Perspective in a Single Image 

      Iizuka, S.; Endo, Y.; Hirose, M.; Kanamori, Y.; Mitani, J.; Fukui, Y. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose an image editing system for repositioning objects in a single image based on the perspective of the scene. In our system, an input image is transformed into a layer structure that is composed of object layers ...

    • Object Space EWA Surface Splatting: A Hardware Accelerated Approach to High Quality Point Rendering 

      Ren, Liu; Pfister, Hanspeter; Zwicker, Matthias (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Elliptical weighted average (EWA) surface splatting is a technique for high quality rendering of point-sampled 3D objects. EWA surface splatting renders water-tight surfaces of complex point models with high quality, ...

    • An Object-Oriented Approach to Process Monitoring 

      Hütter, Ronald (Eurographics Association, 1988)
      Current and future user interface requirements of process monitoring applications are summarized. An object-oriented approach to meet these requirements is described. A special displayfile structure, the socalled object-oriented ...

    • Object-Oriented Data Modelling for Graphics Databases: a Declarative Approach 

      Bhalla, Neelam; Balasundaram, S. (Blackwell Science Ltd and the Eurographics Association, 1991)
      This paper presents a new scheme to integrate the declarative approach to graphics and object-oriented data modelling techniques to form a fruitful symbiosis for constraint-based graphics database systems. It has rich ...

    • An Object-Oriented View of the User Interface 

      Zhou, Tom Z.-Y.; Kubitz, William J. (Blackwell Science Ltd and the Eurographics Association, 1992)
      The object-oriented view of the user interface presented here is a model of object responsibilities-sharing and cooperation for a typical user interface. The model regards the user interface as a three-layer architecture, ...

    • Object-Space Visibility Ordering for Point-Based and Volume Rendering 

      Hofsetz, C.; Max, N.; Bastos, R. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a method to accelerate algorithms that need a correct and complete visibility ordering of their data for rendering. The technique works by pre-sorting primitives in object-space using three lists (one ...

    • An Objective Deghosting Quality Metric for HDR Images 

      Tursun, Okan Tarhan; Akyüz, Ahmet Oğuz; Erdem, Aykut; Erdem, Erkut (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Reconstructing high dynamic range (HDR) images of a complex scene involving moving objects and dynamic backgrounds is prone to artifacts. A large number of methods have been proposed that attempt to alleviate these artifacts, ...
