To solve some critical issues raised by anastylosis techniques, such as the deterioration of the original fragments due to continuous handling, and to compare alternative matching solutions for choosing the best one for real restoration, the pattern recognition and computer vision communities are proposing approaches that work on virtual copies of the fragments, providing new methodologies that help in the matching task. In this paper, we present Javastylosis, a tool that can support restorers for reassembling 2D images of damaged frescoes. With this computer-assisted methodology the user can apply chromatic and semantics principles. Each virtual fragments can be moved and rotated, and the same operations can be applied on groups of fragments. During the matching task, spurious elements can be discarded, and the final result is a digital solution of the 'puzzles' made by the artwork fragments, providing a table of coordinates useful to the restorers to correctly reposition the real fragments. The graphical interface, designed to be easy and intuitive, has been studied for and tested by people belonging to the autism spectrum but with very acute visual skills, so that inclusion opportunities can be given to this group of disadvantaged people.

This paper provides a brief introduction to an instructional method called “Experiential Learning”, assessed and partially readjusted in an undergraduate computer engineering class, largely mediated by the use of multimedia learning technologies. The approach followed in planning and designing the “Computer vision” course goes through different modalities: traditional lectures in class introduce the key elements, while students independently access additional content, delivered on-line, at home. Later, time in class is devoted to active learning, problem solving and instructor-guided discussions to enhance the subject understanding. The goal is to improve the students’ engagement with learning, focusing on the cycle: thinking, planning, implementing, testing and reflecting to tackle a complex problem. The proposed case-study is about the 3D reconstruction of an articulated sculpture dated 1362, the Ark of St. Agostino, located in Pavia in the church of San Pietro in Ciel d’Oro. The ...

The advantages of programmable massively parallel fine-grained machines for vision applications are well known. During the design of a new one, the study of its behavior and performance (through simulation) is paramount to achieve optimum tailoring. Furthermore, software development demands convenient tools to achieve maximum results from the machine capabilities and the efforts of the programmer.

ABSTRACT Asolemn centenary celebration of Alessandro Volta's university chair was held at the University of Pavia in April 1878. To celebrate this important event, Pavia organized a sumptuous ceremony, with vast echoes both in Italy and abroad. To immortalize the great scientist, a statue was inaugurated in the University courtyard by the Prime Minister, Benedetto Cairoli (a hero of Italian unification), with the backing of Francesco De Sanctis, Minister for National Education.

Playing music with the eyes is a challenging task. In this paper, we propose a virtual digital musical instrument, usable by both motor-impaired and able-bodied people, controlled through an eye tracker and a "switch". Musically speaking, the layout of the graphical interface is isomorphic, since the harmonic relations between notes have the same geometrical shape regardless of the key signature of the music piece. Four main design principles guided our choices, namely: (1) Minimization of eye movements, especially in case of large note intervals; (2) Use of a grid layout where "nodes" (keys) are connected each other through segments (employed as guides for the gaze); (3) No need for smoothing filters or time thresholds; and (4) Strategic use of color to facilitate gaze shifts. Preliminary tests, also involving another eye-controlled musical instrument, have shown that the developed system allows "correct" execution of music pieces even when characterized by complex melodies.
