      The ideas underlying a Painting System being developed at the University of Bath are introduced. This differs from a conventional system in that ultra high definition pictures of upto 1 gigabyte may be created. We discuss ...
    • Ultrasound Decompression for Large Field-of-View Reconstructions 

      Schulte zu Berge, Christian; Salehi, Mehrdad; Bender, Frederik; Wein, Wolfgang (The Eurographics Association, 2018)
      Tracked medical ultrasound allows for cost-effective and radiation-free imaging of anatomy featuring a very high spatial resolution. To overcome the limitations of the small field-of-view, sonographers can acquire multiple ...
    • Ultrasound Painting of Liver Vascular Tree 

      Birkeland, Asmund; Viola, Ivan (The Eurographics Association, 2010)
      In treatment planning and surgical interventions, physicians and surgeons need information about the spatial extent of specific features and the surrounding structures. Previous techniques for extracting features, based ...
    • Uma aplicação móvel para implementar o conceito de caderneta de cromos aos Museus 

      Costa, Luís; Coelho, António (The Eurographics Association, 2020)
      No âmbito do património cultural, os museus são uma peça central. No entanto, carecem de atualização face às necessidades de experiências mais interativas, de forma a cativar um público mais jovem. Tendo como caso de estudo ...
    • Un Algoritmo de Muestreo exacto para BRDFs Arbitrarias 

      Montes, R.; Urena, C.; Lastra, M.; Garcia, R. (The Eurographics Association, 2008)
      Este trabajo presenta un algoritmo para el muestreo eficiente y exacto de BRDF genéricas, esto es, apto para cualquiera de los modelos de BRDFs analíticos o adquiridos de la literatura de informática gráfica. Nuestro ...
