    • Backwards Compatible JPEG Stereoscopic High Dynamic Range Imaging 

      Selmanovic, Elmedin; Debattista, Kurt; Bashford-Rogers, Thomas; Chalmers, Alan (The Eurographics Association, 2012)
      In this paper we introduce Stereoscopic High Dynamic Range (SHDR) Imagery which is a novel tecnique that combines high dynamic range imaging and stereoscopy. Stereoscopic imaging captures two images representing the views ...

    • Evaluation of the compressibility of Computer-Generated Holograms 

      Pimenta, Waldir; Santos, Luis P. (The Eurographics Association, 2015)
      We present a preliminary investigation of the compressibility of Physically-Based Computer-Generated Holograms (PB CGHs) as represented in various bases. The goal is to identify which bases, if any, are suitable for applying ...

    • MTV-Player: Interactive Spatio-Temporal Exploration of Compressed Large-Scale Time-Varying Rectilinar Scalar Volumes 

      Díaz, Jose; Marton, Fabio; Gobbetti, Enrico (The Eurographics Association, 2019)
      We present an approach for supporting fully interactive exploration of massive time-varying rectilinear scalar volumes on commodity platforms. We decompose each frame into a forest of bricked octrees. Each brick is further ...

    • Real-time Deblocked GPU Rendering of Compressed Volumes 

      Marton, Fabio; Guitián, José A. Iglesias; Díaz, Jose; Gobbetti, Enrico (The Eurographics Association, 2014)
      The wide majority of current state-of-the-art compressed GPU volume renderers are based on block-transform coding, which is susceptible to blocking artifacts, particularly at low bit-rates. In this paper we address the ...

    • Stochastic Depth Buffer Compression using Generalized Plane Encoding 

      Andersson, Magnus; Munkberg, Jacob; Akenine-Möller, Tomas (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, we derive compact representations of the depth function for a triangle undergoing motion or defocus blur. Unlike a static primitive, where the depth function is planar, the depth function is a rational ...

    • A Survey of Compressed GPU-Based Direct Volume Rendering 

      Rodríguez, Marcos Balsa; Gobbetti, Enrico; Guitián, José A. Iglesias; Makhinya, Maxim; Marton, Fabio; Pajarola, Renato; Suter, Susanne K. (The Eurographics Association, 2013)
      Great advancements in commodity graphics hardware have favored GPU-based volume rendering as the main adopted solution for interactive exploration of rectilinear scalar volumes on commodity platforms. Nevertheless, long ...

    • Towards Efficient Online Compression of Incrementally Acquired Point Clouds 

      Golla, Tim; Schwartz, Christopher; Klein, Reinhard (The Eurographics Association, 2014)
      We present a framework for the online compression of incrementally acquired point cloud data. For this, we extend an existing vector quantization-based offline point cloud compression algorithm to handle the challenges ...
