DOCUMENTING PAINTINGS USING GIGAPIXEL SFM PHOTOGRAMMETRY [PDF]
Abstract. Capturing paintings with gigapixel resolution (resolution around 1000 megapixels or greater) is an innovative technique that is starting to be used by some important international museums for documenting, analysing, and disseminating their masterpieces.This line of research is extremely interesting, not only for art curators and scholars, but

Characterising vent and crater shape changes at Stromboli: implications for risk areas
Active volcanoes are typically subject to frequent substantial topographic changes as well as variable eruption intensity, style and/or directionality. Gravitational instabilities and local accumulation of pyroclasts affect conditions at the active vents,

Video Registration to SfM Models [PDF]
Registering image data to Structure from Motion (SfM) point clouds is widely used to find precise camera location and orientation with respect to a world model. In case of videos one constraint has previously been unexploited: temporal smoothness. Without temporal smoothness the magnitude of the pose error in each frame of a video will often dominate ...
