      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 ...
    • 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 ...
    • Un Método para la Detección en Tiempo Real de Perturbaciones Fotométricas en Imágenes Proyectadas 

      Garay, Miguel Castañeda; Fernández, Óscar Belmonte; Altaba, Jose Gil; Rosés, Hebert Pérez; Coma, Inmaculada (The Eurographics Association, 2009)
      Los sistemas de pantallas de proyección han ganado gran popularidad en los últimos años, principalmente por el gran tamaño de pantalla y resolución que brindan, así como por las facilidades de visión estereoscópica que los ...
    • Un sistema de caché para la visualización interactiva de campos de luz de alta resolución 

      Escrivá, Miguel; Blasco, Joan; Abad, Paco; Camahort, Emilio; Vivó, Roberto (The Eurographics Association, 2009)
      Los modelos de visualización basados en campos de luz almacenan valores de radiancia muestreados a lo largo de un conjunto de lineas orientadas en un espacio 4-dimensional. Esta elevada dimensionalidad junto al hecho de ...
    • Unambiguous Analysis of Woman Breast Shape for Plastic Surgery Outcome Evaluation
