      Conference report
      Open Access
      Structure-from-motion along with multi-view stereo techniques jointly allow for the inexpensive scanning of 3D objects (e.g. buildings) using just a collection of images taken from commodity cameras. Despite major advances ...
    • Development of general-purpose projection-based augmented reality systems 

      Sunet Pérez, Marc; Comino Trinidad, Marc; Karatzas, Dimosthenis; Chica Calaf, Antonio; Vázquez Alcocer, Pere Pau (2016-12-20)
      Article

      Despite the large amount of methods and applications of augmented reality, there is little homogenizatio n on the software platforms that support them. An exception may be the low level control software that is provided ...
    • Easy authoring of image-supported short stories for 3D scanned cultural heritage 

      Comino Trinidad, Marc; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio (European Association for Computer Graphics (Eurographics), 2020)
      Conference report
      Open Access
      Visual storytelling is a powerful tool for Cultural Heritage communication. However, traditional authoring tools either produce videos that cannot be fully integrated with 3D scanned models, or require 3D content creation ...
    • Effective visualization of sparse image-to-image correspondences 

      Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Comino Trinidad, Marc (European Association for Computer Graphics (Eurographics), 2020)
      Conference report
      Open Access
      Finding robust correspondences between images is a crucial step in photogrammetry applications. The traditional approach to visualize sparse matches between two images is to place them side-by-side and draw link segments ...
    • Error-aware construction and rendering of multi-scan panoramas from massive point clouds 

      Comino Trinidad, Marc; Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Brunet Crosa, Pere (2016-09-30)
