    In the last decade a new family of methods, namely Image-Based Rendering, has appeared. These techniques rely on the use of precomputed images to totally or partially substitute the geometric representation of the scene. ...
  • Image-based modeling using viewpoint entropy 

    Vázquez Alcocer, Pere Pau; Feixas, Miquel; Sbert Cassasayas, Mateu; Heidrich, Wolfgang (2002)
    Conference report
    Open Access
    We present a new method to automatically determine the correct camera placement positions in order to obtain a minimal set of views for Image-Based Rendering. The viewpoints should cover all visible polygons with an adequate ...
