    • HDR Photographic Pipeline for Camera Modules in Mobile Devices 

      Mantiuk, R.; Cybularczyk, J.; Cichowicz, M.; Smyk, M.; Bazyluk, B. (The Eurographics Association, 2011)
      We replace the standard image capture pipeline in mobile phones with an HDR acquisition pipeline based on the multi-exposure method. We report timings for basic HDR algorithms implemented in a smartphone with ARMv6 processor ...
    • Towards Mobile HDR Video 

      Castro, T. K.; Chapiro, A.; Cicconet, M.; Velho, L. (The Eurographics Association, 2011)
      We present a novel method for High Dynamic Range video where the critical phases of the pipeline are based on histograms. It is possible to achieve high framerates, since the algorithm generates one HDR frame per captured ...
    • High-Quality Tactile Paintings 

      Reichinger, A.; Maierhofer, S.; Purgathofer, W. (The Eurographics Association, 2011)
      The aim of this work is to bring the cultural heritage of two-dimensional art closer to being accessible by blind and visually impaired people. We present a computer-assisted workflow for the creation of tactile representations ...
    • A Streaming Framework for Seamless Detailed Photo Blending on Massive Point Clouds 

      Pintus, Ruggero; Gobbetti, Enrico; Callieri, Marco (The Eurographics Association, 2011)
      We present an efficient scalable streaming technique for mapping highly detailed color information on extremely dense point clouds. Our method does not require meshing or extensive processing of the input model, works on ...
    • Multispectral Image Matting of Ancient Chinese Paintings 

      Zhang, Jiawan; Zhang, Yi; Zhang, Shengping; Yan, Lixia; Chen, Jinyan (The Eurographics Association, 2011)
      Digital matting, the process of extracting a foreground object from an image, is an important task in image and video editing. Applying matting techniques to Chinese painting image processing can create novel composites ...
    • Synthesizing Relative Radiance for Realistic Rendering of Virtual Objects in 3D Photo Collections 

      Kölzer, K.; Nagl, F.; Grimm, P. (The Eurographics Association, 2011)
      We present a novel approach for accurate reconstruction of relative radiance of every surface in an augmented image-based 3D scene. By using unordered images with varying exposure of 3D Photo Collections and a 3D mesh of ...
    • Relightable Buildings from Images 

      Melendez, F.; Glencross, M.; Ward, G. J.; Hubbold, R. J. (The Eurographics Association, 2011)
      We propose a complete image-based process that facilitates recovery of both gross-scale geometry and local surface structure to create highly detailed 3D models of building façades from photographs. We approximate both ...
    • Learning How to Match Fresco Fragments 

      Funkhouser, T.; Shin, H.; Toler-Franklin, C.; Castañeda, A. García; Brown, B.; Dobkin, D.; Rusinkiewicz, S.; Weyrich, T. (The Eurographics Association, 2011)
      One of the main problems faced during reconstruction of fractured archaeological artifacts is sorting through a large number of candidate matches between fragments to find the relatively few that are correct. Previous ...
    • Photographically Guided Alignment for HDR Images 

      Akyüzy, Ahmet Oguz (The Eurographics Association, 2011)
      This paper presents an automatic image alignment algorithm that alleviates the need to keep the camera still during the capture of a bracketed sequence to obtain an HDR image. Our algorithm assumes that the misalignment ...
    • Rendering Interior Cultural Heritage Scenes Using Image-based Shooting 

      Happa, Jassim; Bashford-Rogers, Tom; Debattista, Kurt; Chalmers, Alan (The Eurographics Association, 2011)
      Rendering interior cultural heritage scenes using physically based rendering with outdoor environment maps is computationally expensive using ray tracing methods, and currently difficult for interactive applications without ...
    • Using Procedural Modelling as a Framework for Representing Style: An Example from Regency Architecture 

      Calogero, Erica; Tyson, Nick; Arnold, David; Morris, David (The Eurographics Association, 2011)
      This paper reports the use of shape grammars, as made available in CityEngine, to deconstruct six examples of Regency facades and uses them to form a reconstruction of Brunswick Square, in Brighton & Hove, UK. The aim of ...
    • Avoiding Chromaticity Creep with PseudoGrey 

      Grimstead, I. J.; Avis, N. J. (The Eurographics Association, 2011)
      We examine the calibration of Commodity, Off-The-Shelf (COTS) monitors to the DICOM GreyScale Display Function (GSDF) standard (as used for medical imaging). We note that uncalibrated and calibrated (using commercial and ...
    • Enhancement of Low Dynamic Range Videos using High Dynamic Range Backgrounds 

      Banterle, Francesco; Dellepiane, Matteo; Scopigno, Roberto (The Eurographics Association, 2011)
      In this paper, we present a practical system for enhancing the quality of Low Dynamic Range (LDR) videos using High Dynamic Range (HDR) background images. Our technique relies on the assumption that the HDR information is ...
