    • Temporally Consistent Motion Segmentation From RGB‐D Video 

      Bertholet, P.; Ichim, A.E.; Zwicker, M. (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Temporally consistent motion segmentation from RGB‐D videos is challenging because of the limitations of current RGB‐D sensors. We formulate segmentation as a motion assignment problem, where a motion is a sequence of rigid ...

      Based on a new spectral vector field analysis on triangle meshes, we construct a compact representation for near conformal mesh surface correspondences. Generalizing the functional map representation, our representation ...

    • Visually Supporting Multiple Needle Placement in Irreversible Electroporation Interventions 

      Kreiser, J.; Freedman, J.; Ropinski, T. (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Irreversible electroporation (IRE) is a minimally invasive technique for small tumour ablation. Multiple needles are inserted around the planned treatment zone and, depending on the size, inside as well. An applied electric ...

      Aristidou, A.; Lasenby, J.; Chrysanthou, Y.; Shamir, A. (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Inverse kinematics (IK) is the use of kinematic equations to determine the joint parameters of a manipulator so that the end effector moves to a desired position; IK can be applied in many areas, including robotics, ...

      The use of Laplacian eigenfunctions is ubiquitous in a wide range of computer graphics and geometry processing applications. In particular, Laplacian eigenbases allow generalizing the classical Fourier analysis to manifolds. ...

    • Feature of Interest‐Based Direct Volume Rendering Using Contextual Saliency‐Driven Ray Profile Analysis 

      Jung, Y.; Kim, J.; Kumar, A.; Feng, D.D.; Fulham, M. (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Direct volume rendering (DVR) visualization helps interpretation because it allows users to focus attention on the subset of volumetric data that is of most interest to them. The ideal visualization of the features of ...

    • Sensor-aware Normal Estimation for Point Clouds from 3D Range Scans 

      Comino Trinidad, Marc; Andujar, Carlos; Chica, Antonio; Brunet, Pere (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Normal vectors are essential for many point cloud operations, including segmentation, reconstruction and rendering. The robust estimation of normal vectors from 3D range scans is a challenging task due to undersampling and ...
