    (The Eurographics Association, 2011) Silvestro, Lorenzo Di; Gallo, Giovanni; Giuffrida, Giovanni; Zarba, Calogero; Andrea F. Abate and Michele Nappi and Genny Tortora
    Today everyone on the Internet becomes an active writer. It is simpler than ever to produce and to share new knowledge on the net. Users risk to be overwhelmed by too such information. To handle unorganized data may involve a huge effort by people and this could lead to information overload. A promising way to face these problems is Information Visualization. This contribution is a report of using visuo-spatial reasoning to help sociology scholars to understand and to manage large amounts of textual data. We use a very interesting dataset, especially for sociologists and jurists, extracted from a collection of sentences of trials on organized crime activities in Sicily. We report the results obtained in so far clustering and visualizing data.

    3D Reconstruction and Augmented Reality in Bronchoscopic Intervention
    (The Eurographics Association, 2011) Torrisi, Alessandro; Livatino, Salvatore; Gallo, Giovanni; Andrea F. Abate and Michele Nappi and Genny Tortora
    The use of stereoscopic visualization has recently been proposed for many applications. Other than for entertainment, stereo viewing is being proposed for robotics and medical teleoperation. This paper proposes to exploit the stereo-camera setup available in stereo-viewing systems for 3D reconstruction. We focus on medical endoscopic applications. The advantages of having a reconstructed vision-based depth map during endoscopic navigation and intervention are many, including the possibility for generation of an augmented-reality visual scenario to support surgeons during interventions. We ran our experiments on a realistic graphic model of human bronchus to study feasibility of the proposed concept. We reconstructed depth maps of a bronchus environment and used them to generate augmented reality views of the observed scenes.
