Piecewise planar underwater mosaicing

2015

A commonly ignored problem in planar mosaics, yet often present in practice, is the selection of a reference homography reprojection frame where to attach the successive image frames of the mosaic. A bad choice for the reference frame can lead to severe distortions in the mosaic and can degenerate in incorrect configurations after some sequential frame concatenations. This problem is accentuated in uncontrolled underwater acquisition setups as those provided by AUVs or ROVs due to both the noisy trajectory of the acquisition vehicle — with roll and pitch shakes — and to the non-flat nature of the seabed which tends to break the planarity assumption implicit in the mosaic construction. These…

A Programmable Networked Processing Node for 3D Brain Vessels Reconstruction

2011

Real-time 3D imaging represents a developing trend in medical imaging. However, most of the 3D medical imaging algorithms are computationally intensive. In this paper, a programmable networked node for 3D brain vessels reconstruction is proposed. Starting from 2D PC-MRA (Phase-Contrast Magnetic Resonance Angiography) sequences, the node is able to generate the 3D brain vasculature using the MIP (Maximum Intensity Projection) algorithm. The node has been prototyped on the Celoxica RC203E board, equipped with a Virtex II FPGA, to get the advantages of an hardware implementation, reaching a better throughput with respect to analogous software implementations. Its generality and programmable ca…

Fast Volumetric Reconstruction of Human Body through Superquadrics

2013

This paper describes a technique to reconstruct the volumes of the human body. For this purpose, are introduced mathematical objects able to represent 3d shapes, called super quadrics. These objects are positioned in the space according the captures made by a Microsoft Kinect device and are composed to represent the volumes of the human body. The employment of quaternions provides a relevant speedup for the rotation of the volumes and allows to follow the human movements in real time and reduced computational cost.

Come il diritto inventa le identità

2012

Does the identity recorded by documents certify what you are or affect your way of being? Do the different classes of subjects to which the rules grant rights or impose obligations exist before being utilized by law? Is the role conferred by the institutions a false mask that can be dismissed at the end of a working day or is it a stubborn demon that possesses the soul of the man and the citizen? These questions introduce the issue of this paper: the relationship between Law and identity, in particular the contribution of legal sphere to the construction or manipulation of collective identities such as gender, race, nationality or class. The author opts for a constructivist approach and des…

Lettura stratigrafica delle murature e studio architettonico della Chiesa

2018

The contribution concerns the study of the construction phases of the church of Santa Marina in Muro Leccese (LE) realized through the stratigraphic reading of the masonry that has allowed, later, to be able to carry out the reconstructive study of the building through a digital model.

Dallo scavo archeologico alla riprogettazione virtuale di un edificio: La chiesa a doppia abside del casale di Quattro Macine, Giuggianello (Lecce)

2003

The increasingly widespread use of computational technologies in the archaeological field it has opened up new possibilities of research thanks to the passage of information technology from simple support for "management and documentation" of data as a tool for the "production and analysis" of data themselves. Nowadays, having new software from computer-aided architectural design (Computer Aided Design) it is possible for the archaeologist to use the computer to realize a virtual reconstruction intended as a tool of archaeological analysis of an artifact building, retracing all the individual steps of the activity constructive up to the original architectural project. To proceed in this wor…

Ricerche a Solunto (2022)

2023

New Investigations at Solunto (2022) ∙ The last fieldwork campaign in Solunto by the University of Palermo, in the sanctuary above the theatre and in the baths near the agora (the North Baths), obtained some relevant results concerning both the building sequences and the architectural configurations. In the sanctuary, a clearer picture is emerging of the oldest layout, dating from the 4th century B.C. (1st phase). After the first reshaping of the street grid and of the urban layout (2nd phase), in the second half of 2nd century B.C., an overall restyling (3rd phase) gave the whole sanctuary area an impressive organization into terraces linked through ramps and stairways. A striking feature,…

Architettura e Informatica. Il tempio della gens flavia a Leptis Magna

2016

This paper illustrates the pursuance of the studies, focused on the initial phases of the Flavian Temple in Leptis, until 2014. The reconstructive hypothesis by the arch. Paolo Mighetto, based on the old and new archaeological data as result of excavations and researches in recent years, allow to publish the first 3d virtual rendering of the Roman Complex, made by Dr. Massimo Limoncelli, member of the Italian-Libian Archaeological Mission
