Study of Influence of the LED Technologies on Visual and Subjective/Individual Aspects
2018
The general aim of this paper is that to further deepen and elaborate the results obtained in a previous study of the authors, in which the relationship between the characteristics of five different types of LED lamps and the humans non-image-forming reactions were investigated, by conducting a more detailed statistical analysis and by highlighting the neurological aspects.
Blood vessels and feature points detection on retinal images
2009
In this paper we present a method for the automatic extraction of blood vessels from retinal images, while capturing points of intersection/overlap and endpoints of the vascular tree. The algorithm performance is evaluated through a comparison with handmade segmented images available on the STARE project database (STructured Analysis of the REtina). The algorithm is performed on the green channel of the RGB triad. The green channel can be used to represent the illumination component. The matched filter is used to enhance vessels w.r.t. the background. The separation between vessels and background is accomplished by a threshold operator based on gaussian probability density function. The len…
Unsupervised Clustering in Personal Photo Collections
2008
In this paper we propose a probabilistic approach for the automatic organization of collected pictures aiming at more effective representation in personal photo albums. Images are analyzed and described in two representation spaces, namely, faces and background. Faces are automatically detected, rectified and represented projecting the face itself in a common low dimensional eigenspace. Backgrounds are represented with low-level visual features based on RGB histogram and Gabor filter energy. Face and background information of each image in the collection is automatically organized by mean-shift clustering technique. Given the particular domain of personal photo libraries, where most of the …
Methods and Techniques for Multi-source Data Analysis and Fusion
This work has been inspired by the recent trend in remote sensing and environmental data acquisition. Remote sensing techniques allow us to measure information about an object without touching it. In the last decades remote sensing via satellites has been used in various applications such as Earth observation, weather and storm predictive analysis, atmospheric monitoring, climate change, human-environment interactions. Sensors on airborne and satellite platforms have been recording signals from space for many years, giving rise to a huge amount of data. Some data are processed on-board but others are treated and post-processed in ground stations. Signal and image processing are widely appli…
Mean shift clustering for personal photo album organization
2008
In this paper we propose a probabilistic approach for the automatic organization of pictures in personal photo album. Images are analyzed in term of faces and low-level visual features of the background. The description of the background is based on RGB color histogram and on Gabor filter energy accounting for texture information. The face descriptor is obtained by projection of detected and rectified faces on a common low dimensional eigenspace. Vectors representing faces and background are clustered in an unsupervised fashion exploiting a mean shift clustering technique. We observed that, given the peculiarity of the domain of personal photo libraries where most of the pictures contain fa…
«Un vero e proprio film»: Longhi, Briganti e La Maniera italiana (1961)
2021
Il saggio propone un'analisi dettagliata del percorso editoriale del volume «La Maniera italiana» che Giuliano Briganti pubblica nel 1961 come primo volume di una collana di libri interamente illustrati a colore, redatti da Editori Riuniti insieme a Verlag der Kunst (Dresda, RDT). Grazie a inedite fonti d'archivio questo studio ricostruisce la storia di un singolare episodio di divulgazione storico-artistica che vede Roberto Longhi nella veste di direttore editoriale, affiancato dal critico d'arte Antonio Del Guercio in qualità di segretario redazionale. The essay offers a detailed analysis of Giuliano Briganti's book «La Maniera italiana», which was published in 1961 as the first volume of…
Utopie egualitarie e riformismo illuminato nella Carestia di Domenico Tempio
2022
La Carestia of the Sicilian poet Domenico Tempio is an allegorical satirical poem that fits into the tradition of southern enlightened reformism, feeding the utopia of peace and social egalitarianism. The article analyzes some frame of the work to grasp the thrust for the renewal of eighteenth-century poetry, through a stylistic use of the poetic language that oscillates between coloriture markedly expressionist and equally visible traces of formal classicism.

The prognostic role of KRAS and BRAF in patients undergoing surgical resection of colorectal cancer liver metastasis: a systematic review and meta-an…
2016
Background: Clinical trials investigated the potential role of both KRAS and BRAF mutations, as prognostic biomarkers, in colorectal cancer (CRC) patients who underwent surgical treatment of liver metastasis (CLM), showing conflicting results. This meta-analysis aims to review all the studies reporting survival outcomes (recurrence free survival (RFS), and/or overall survival (OS)) of patients undergoing resection of CLM, stratified according to KRAS and/or BRAF mutation status. Materials and Methods: Data from all published studies reporting survival outcomes (RFS and/or OS) of CRC patients who received resection of CLM, stratified by KRAS and/or BRAF mutation status were collected by sear…
