      This paper is an analysis of the recording, processing and presentation of the 3D data of two late Roman towers, through mast and zeppelin photography and image-based modelling software (IBM). Comparison is made to traditional ...
    • Recovering 3-D Shape and Reflectance From a Small Number of Photographs 

      Georghiades, Athinodoros S. (The Eurographics Association, 2003)
      There are computer graphics applications for which the shape and reflectance of complex objects, such as faces, cannot be obtained using specialized equipment due to cost and practical considerations. We present an imagebased ...
    • Recovering 3D architectural information from dense digital models of buildings

      We present a novel approach to automatically recover, from a small set of partially overlapping panoramic images, an indoor structure representation in terms of a 3D floor plan registered with a set of 3D environment maps. ...
    • Recovering a Smooth Boundary Representation from an Edge Quadtree and from a Face Octree 

      Pla-Garcia, N. (Blackwell Science Ltd and the Eurographics Association, 1994)
      The Face Octrees are a representation scheme which is very suitable to represent both smooth free form surfaces and solids with smooth boundary, as well as, to perform operations among them. However, the Face Octree ...
    • Recovering Geometric Information with Learned Texture Perturbations 

      Wu, Jane; Jin, Yongxu; Geng, Zhenglin; Zhou, Hui; Fedkiw, Ronald (ACM, 2021)
      Regularization is used to avoid overfitting when training a neural network; unfortunately, this reduces the attainable level of detail hindering the ability to capture high-frequency information present in the training ...
    • Recovering Intrinsic Images by Minimizing Image Complexity 

      Stefani, Nicola; Fusiello, Andrea (The Eurographics Association, 2015)
      This paper tackles the problem of decomposing a single image into two intrinsic images - a shading image (the illumination at each point) and a reflectance image (the colour at each point). Assuming a linear response of ...
