Fusion of computed point clouds and integral-imaging concepts for full-parallax 3D display
2020
During the last century, various technologies of 3D image capturing and visualization have spotlighted, due to both their pioneering nature and the aspiration to extend the applications of conventional 2D imaging technology to 3D scenes. Besides, thanks to advances in opto-electronic imaging technologies, the possibilities of capturing and transmitting 2D images in real-time have progressed significantly, and boosted the growth of 3D image capturing, processing, transmission and as well as display techniques. Among the latter, integral-imaging technology has been considered as one of the promising ones to restore real 3D scenes through the use of a multi-view visualization system that provi…
Integration of large-area optical imagers for biometric recognition and touch in displays
2021
In recent years there has been an increasing interest to integrate optical sensing in mobile displays, for instance, for biometric fingerprint scanning functionality. There are several routes to incorporate optical fingerprint functionality within the full display area, each with their own benefits and challenges. Here we investigate the different integration routes using large-area, ultra-thin imagers based on organic photodiodes.
Valutazione formativa e didattica a distanza all’Università
2021
La valutazione per l’apprendimento (assessment for learning) e la valutazione come apprendimento (assessment as learning) sono concetti che recentemente hanno assunto un ruolo centrale nella letteratura sull’argomento. Il contributo illustra, dopo una esplicitazione delle caratteristiche dei due approcci, un’esperienza di valutazione per l’apprendimento e come apprendimento in Università. La ricerca si propone di descrivere come 125 studenti del corso di Laurea Magistrale di Scienze della Formazione Primaria dell’Università di Palermo partecipino abitualmente al processo di valutazione e percepiscano l’utilità della valutazione formativa e i benefici del ricevere feedback. I dati raccolti …
A Dataset of Annotated Omnidirectional Videos for Distancing Applications
2021
Omnidirectional (or 360°) cameras are acquisition devices that, in the next few years, could have a big impact on video surveillance applications, research, and industry, as they can record a spherical view of a whole environment from every perspective. This paper presents two new contributions to the research community: the CVIP360 dataset, an annotated dataset of 360° videos for distancing applications, and a new method to estimate the distances of objects in a scene from a single 360° image. The CVIP360 dataset includes 16 videos acquired outdoors and indoors, annotated by adding information about the pedestrians in the scene (bounding boxes) and the distances to the camera of some point…

Clinical evaluation of automated capillary refill time estimation in dogs and cats
2019
In this study, we clinically evaluated a pulse oximeter-based device for automated capillary refill time (CRT) estimation in dogs and cats. CRT can reveal conditions like shock or anemia in dogs and cats. However, visual CRT estimation has low repeatability, and the available optical systems for automated estimation are not suitable for pets. We evaluated a custom-made portable CRT measuring device on various measurement sites of 12 dogs and 11 cats with parallel visual CRT estimation on the gum by treating veterinarian. The capillary refill was also recorded by a video camera for reference. The visual and video procedures were moderately correlated with the coefficient of 0.61; visual CRT …
Nonlinear Time-Series Adaptation for Land Cover Classification
2017
Automatic land cover classification from satellite image time series is of paramount relevance to assess vegetation and crop status, with important implications in agriculture, biofuels, and food. However, due to the high cost and human resources needed to characterize and classify land cover through field campaigns, a recurrent limiting factor is the lack of available labeled data. On top of this, the biophysical–geophysical variables exhibit particular temporal structures that need to be exploited. Land cover classification based on image time series is very complex because of the data manifold distortions through time. We propose the use of the kernel manifold alignment (KEMA) method for…

Storie di donne migranti in Sicilia. Discriminazioni, confinamenti, e inclusioni differenziali nel mercato del lavoro
2015
L'articolo guarda alle dinamiche della femminilizzazione delle migrazioni analizzate dalla principale letteratura sul tema per come esse si declinano nel contesto siciliano contemporaneo. la difficoltà di pervenire a una effettiva "integrazione" delle donne in Sicilia è narrata a partire dalla critica dello stesso concetto di "integrazione" e attraverso da una serie di interviste in profondità che analizzano la condizione di donne migranti con storie e provenienze molto differenti tra loro. Le interviste sono state raccolte nelle Provincie di Palermo e di Ragusa.
Narrazioni al femminile di Cosa Nostra
2010
Starting from the analysis of the important transformations that have characterized the roles of women within the criminal world of Cosa Nostra in the last decades, the article focuses on the dimensions of identity and communication through which the belonging of women to the mafia universe or their exclusion from male territories are defined. In the last two decades, the criminal organization, weakened by the many arrests, has increasingly entrusted to women the responsibility to preserve, affirm and reflect its image of power to the outside. In times of emergency, women are considered the most reliable interlocutors. Using direct evidence, interviews, letters and judicial materials, the a…
