      The interaction between a 2D input device (like a mouse or a touchscreen) and a 3D object on the screen with the purpose of examining it in detail is a well-studied interaction problem. The inherent difference in degrees ...
    • IMGD: Image-based Multiscale Global Descriptors of Airborne LiDAR Point Clouds Used for Comparative Analysis 

      Sreevalsan-Nair, Jaya; Mohapatra, Pragyan; Singh, Satendra (The Eurographics Association, 2021)
      Both geometric and semantic information are required for a complete understanding of regions acquired as three-dimensional (3D) point clouds using the Light Detection and Ranging (LiDAR) technology. However, the global ...
    • An Information-theoretic Visual Analysis Framework for Convolutional Neural Networks 

      Shen, Jingyi; Shen, Han-Wei (The Eurographics Association, 2021)
      Despite the great success of Convolutional Neural Networks (CNNs) in Computer Vision and Natural Language Processing, the working mechanism behind CNNs is still under extensive discussion and research. Driven by strong ...
    • LengthNet: Length Learning for Planar Euclidean Curves 

      Or, Barak; Amos, Ido (The Eurographics Association, 2021)
      In this work, we used a deep learning (DL) model to solve a fundamental problem in differential geometry. One can find many closed-form expressions for calculating curvature, length, and other geometric properties in the ...
    • Mesh Colours for Gradient Meshes
