Rebuilding Palermo in the Middle Ages: A Virtual Approach
2020
A long sequence of demolitions, transformations, interpretative restorations eliminated or compromised a series of civil and religious buildings built between the XII and early XVI centuries in Palermo. For many of these architectures, graphic, photographic and documentary evidence exists and can be found. Within an extensive project of the Department of Architecture of the University of Palermo, based on the collaboration between different disciplines, we intend to offer an essay of the possible results that the synergy between historical research and representation can offer. Chosen case is a fifteenth-century civil building located in the San Francesco district, of which some fragments r…
La memoria fotografica dell’architettura : restituzioni prospettiche e ricostruzioni
2023
This book explores perspective restitution from photographs for the reconstruction of buildings and urban sites that no longer exist or have suffered many alterations over time. Digital drawing and modelling tools overcome many of the limitations that, in the past, made perspective restitution from photographs inaccurate and inconvenient. Traditional drawing tools made perspective restitution from photographs difficult, especially when vanishing points appeared at a great distance from the image frame. The results of perspective restitution were either 1D or 2D objects, i.e. points, segments, angles, planar figures and profiles, that were revolved into the picture plane. By contrast, digita…
Convolutional architectures for virtual screening
2020
Abstract Background A Virtual Screening algorithm has to adapt to the different stages of this process. Early screening needs to ensure that all bioactive compounds are ranked in the first positions despite of the number of false positives, while a second screening round is aimed at increasing the prediction accuracy. Results A novel CNN architecture is presented to this aim, which predicts bioactivity of candidate compounds on CDK1 using a combination of molecular fingerprints as their vector representation, and has been trained suitably to achieve good results as regards both enrichment factor and accuracy in different screening modes (98.55% accuracy in active-only selection, and 98.88% …
Visual Culture and Cultural Heritage: ViC-CH a Synthesis Between Digital Representation and Heritage Experience
2019
The dissemination possibilities offered by digital technologies provide multiple ways of reading and fruition of the cultural heritage. In order to define a visualization and communication strategy through images, the paper shows some of the results of the ViC-CH Visual Culture and Cultural Heritage workshop, which involved the University of Trento and the Free University of Bozen-Bolzano. The graphic elaborations focused on the Library of the Priest Seminar in Brixen; photomodelling, short films with drone shots and virtual visits have been some of the ways of manipulating the image for the animation and realistic visualization of a cultural heritage not easily accessible to date (The pape…
Horses and Cowboys on the Contemporary American Stage: The Horse as Prop in Sam Shepard’sKicking a Dead Horseand Sarah Ruhl’sLate: a cowboy song

This comparative essay analyses the dramatic representation of horses in two early twenty-first-century American plays by Sam Shepard and Sarah Ruhl. Both plays bring a horse figure onto the stage ...
Channel Capacity in Psychovisual Deep-Nets: Gaussianization Versus Kozachenko-Leonenko
2020
In this work, we quantify how neural networks designed from biology using no statistical training have a remarkable performance in information theoretic terms. Specifically, we address the question of the amount of information that can be extracted about the images from the different layers of psychophysically tuned deep networks. We show that analytical approaches are not possible, and we propose the use of two empirical estimators of capacity: the classical Kozachenko-Lonenko estimator and a recent estimator based on Gaussianization. Results show that networks purely based on visual psychophysics are extremely efficient in two aspects: (1) the internal representation of these networks dup…
A Posture Sequence Learning System for an Anthropomorphic Robotic Hand
2003
The paper presents a cognitive architecture for posture learning of an anthropomorphic robotic hand. Our approach is aimed to allow the robotic system to perform complex perceptual operations, to interact with an human user and to integrate the perceptions by a cognitive representation of the scene and the observed actions. The anthropomorphic robotic hand imitates the gestures acquired by the vision system in order to learn meaningful movements, to build its knowledge by different conceptual spaces and to perform complex interaction with the human operator.
''Forward to the past''
2012
Carlini, Alessandro | Actis-Grosso, Rossana | Stucchi, Natale | Pozzo, Thierry; International audience; ''Our daily experience shows that the CNS is a highly efficient machine to predict the effect of actions into the future; are we so efficient also in reconstructing the past of an action? Previous studies demonstrated we are more effective in extrapolating the final position of a stimulus moving according to biological kinematic laws. Here we address the complementary question: are we more effective in extrapolating the starting position (SP) of a motion following a biological velocity profile? We presented a dot moving upward and corresponding to vertical arm movements that were masked i…
The Development of Visuo-spatial Memory: How to Remember Location
1992
Recent studies on developmental differences in spatial memory have reported equivocal results. Some found an age-dependent improvement of memory performance whereas others did not. The two studies reported here investigate age differences in memory for visual-spatial information. A picture reconstruction task with simultaneous presentation of scene-like visual-spatial arrangements was used. Subjects had to recognise objects and to reconstruct the initial spatial arrangement. The first study with 5to 10year-olds produced the typical age-dependent improvement in recognising visual material as well as in remembering the locations of specific objects. No effect for age was obtained in memory f…
Sistemi integrati per la visualizzazione immersiva
2015
Il disegno dell’architettura ha, tra i suoi obiettivi disciplinari, quello di “far vedere” lo spazio, sia nelle sue declinazioni temporali, sia in quelle descrittive di forme, luce, colori e materiali, caratteri connotativi che cerca di riprodurre grazie a metodi di proiezione codificati e tecniche di rappresentazione in continuo mutamento. Tra le tecniche di rappresentazione informatica la visualizzazione immersiva consente di ruotare lo sguardo, in tempo reale, all’interno di uno spazio, cercando di superare i limiti della rappresentazione piana, simulando la visione sferica dello spazio. La tecnica può essere utilizzata sia per vedere la realtà esistente, tramite immagini fotografiche, s…
