    • Statistical Mesh Shape Analysis with Nonlandmark Nonrigid Registration 

      Jan Dupej; Vaclav Krajicek; Jana Veleminska; Josef Pelikan (The Eurographics Association, 2014)
      The analysis of shape represented as surface meshes is an important tool in anthropology and biomedicine for the study of aging, post-treatment development or sexual dimorphism. Most approaches rely on nonrigid registration using ...

    • A Statistical Method For Adaptive Stochastic Sampling 

      Purgathofer, Werner (The Eurographics Association, 1986)
      Stochastic sampling is a good alternative to pure oversampling in terms of image quality. A method for adaptively controlling the number of required samples to the complexity of the picture is presented. The quality of the ...

    • A Statistical Method for Surface Detection 

      Smith, Samuel; Williams, Ian (The Eurographics Association, 2015)
      This work presents a new method for 3D surface detection using a statistical dual-region filter. The method improves over traditional 3D surface detection techniques by resolving interfaces between different stochastic ...

    • A Statistical Method for SVBRDF Approximation from Video Sequences in General Lighting Conditions 

      Palma, Gianpaolo; Callieri, Marco; Dellepiane, Matteo; Scopigno, Roberto (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a statistical method for the estimation of the Spatially Varying Bidirectional Reflectance Distribution Function (SVBRDF) of an object with complex geometry, starting from video sequences acquired with fixed but ...

    • A Statistical Model of Human Pose and Body Shape 

      Hasler, N.; Stoll, C.; Sunkel, M.; Rosenhahn, B.; Seidel, H.-P. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Generation and animation of realistic humans is an essential part of many projects in today s media industry. Especially, the games and special effects industry heavily depend on realistic human animation. In this work a ...

    • Statistical Modeling of the 3D Geometry and Topology of Botanical Trees 

      Wang, Guan; Laga, Hamid; Jia, Jinyuan; Xie, Ning; Tabia, Hedi (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We propose a framework for statistical modeling of the 3D geometry and topology of botanical trees. We treat botanical trees as points in a tree-shape space equipped with a proper metric that captures the geometric and the ...

    • Statistical optimization of octree searches 

      Castro, Rener; Lewiner, Thomas; Lopes, Helio; Tavares, Geovan; Bordignon, Alex (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This work emerged from the following observation: usual search procedures for octrees start from the root to retrieve the data stored at the leaves. But as the leaves are the farthest nodes to the root, why start from the ...

    • Statistical Part-based Models for Object Detection in Large 3D Scans 

      Sunkel, Martin (Sunkel, 2013-09-17)
      3D scanning technology has matured to a point where very large scale acquisition of high resolution geometry has become feasible. However, having large quantities of 3D data poses new technical challenges. Many applications ...

    • Statistical Point Geometry 

      Kalaiah, Aravind; Varshney, Amitabh (The Eurographics Association, 2003)
      We propose a scheme for modeling point sample geometry with statistical analysis. In our scheme we depart from the current schemes that deterministically represent the attributes of each point sample. We show how the ...

    • Statistical Simulation of Rigid Bodies 

      Hsu, Shu-Wei; Keyser, John (ACM SIGGRAPH / Eurographics Association, 2009)
      We describe a method for replacing certain stages of rigid body simulation with a statistically-based approximation. We begin by collecting statistical data regarding changes in linear and angular momentum for collisions ...

    • A Statistically-Assisted Sketch-Based Interface for Creating Arbitrary 3-dimensional Faces 

      Gunnarsson, Orn; Maddock, Steve (The Eurographics Association, 2007)
      Creating faces is important in a number of application areas. Faces can be constructed using commercial modelling tools, existing faces can be transferred to a digital form using equipment such as laser scanners, and law ...

    • Statistics-based Motion Synthesis for Social Conversations 

      Yang, Yanzhe; Yang, Jimei; Hodgins, Jessica (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Plausible conversations among characters are required to generate the ambiance of social settings such as a restaurant, hotel lobby, or cocktail party. In this paper, we propose a motion synthesis technique that can rapidly ...

    • STBVH: A Spatial-Temporal BVH for Efficient Multi-Segment Motion Blur 

      Woop, Sven; Afra, Attila T.; Benthin, Carsten (ACM, 2017)
      We present the STBVH, a newapproach for rendering multi-segment motion blur using a bounding volume hierarchy (BVH) that stores both spatial linearly interpolated bounds and temporal bounds. The approach is designed for ...
