Rappresentare il cambiamento. Street art e rigenerazione urbana a Palermo
2018
Da qualche anno Palermo è oggetto di attenzione da parte di artisti che, da varie parti del mondo, hanno scelto la città quale luogo delle proprie sperimentazioni. Tale fermento ha visto il proliferare di interventi di street art, spesso strumenti di denuncia sociale, in edifici abbandonati, zone urbane degradate, lottizzazioni abusive o edificazioni a ridosso della linea di costa. Recently Palermo is the subject of attention by artists who, from various parts of the world, have chosen the city as the place of their experimentations.This ferment has seen the proliferation of street art, often instruments of social denunciation, realised in abandoned buildings, degraded urban areas, illegal …
Gráficas dinámicas interactivas para estadística (26 años después)
2014
This paper briefly reviews the history of dynamic-interactive graphics for statistics, introduces an example of such graphics, and provides a few glimpses as to the current state of things and the future trends we envision. The general conclusion is that dynamic-interactive graphics for statistics are thriving more than ever as they shift from the desktop to the internet. Thus, dynamic-interactive graphics are becoming increasingly important as they: 1) provide non-experts in statistics with the means to carry out analyses on their own; and 2) teach the basic concepts of statistics to students and practitioners with low to moderate mathematics skills. Their increasing popularity makes the l…

The History of ViSta: The Visual Statistics System
2012
ViSta is a project that focuses on dynamic and interactive graphics for statistics and was initiated by the late Forrest W. Young at the beginning of the 1990s. For over approximately 20 years, Forrest and other collaborators, including the authors of this article, have used ViSta for experimenting with these kinds of graphics in different settings, applying them to different scenarios of data and statistical analysis, searching to develop the right combination of features most appropriate in each case. In this time, ViSta evolved quite considerably, going through what we reckon were three different stages, namely: the initial one setting forth the foundations of ViSta; the second period wh…
Visualizing categorical data in ViSta
2003
The modules in the statistical package ViSta related to categorical data analysis are presented These modules are: visualization of frequency data with mosaic and bar plots, correspondence analysis, multiple correspondence analysis and loglinear analysis. All these methods are implemented in ViSta with a big emphasis on plots and graphical representations of data, as well as interactivity for the user with the system. These provide a system that has shown to be easy, useful, and powerful, both for novice and experienced users.
Panel Summary One Model for Vision Systems?
1994
This panel reports some considerations about the definition of vision-models. The panellists are scientists working on vision problems from different perspectives. The concept of model in vision seems to remain still open. In fact, it is dynamic, and context dependent. There exists the need for a better exchange of information, among biologists, engineers, physicists, and psychologists in order to improve our knowledge.
Attraversare
2016
L'articolo propone alcune riflessioni sul concetto di "attraversamento dell'architettura" tramite l'implicazione delle arti visuali e del teatro danza. In particolare, è stata approfondito tale concetto realizzando un "attraversamento" della concatenazione spaziale di Palazzo Riso, Museo d'Arte Contemporanea di Palermo, filtrando lo spazio con la scansione temporale della danza. La performance di teatro danza prende avvio in un precedente momento architettonico, cioè nella Piazza Bologni, che costituisce una delle due estremità del percorso teatrale-spaziale. La piazza costituisce il momento della riflessione, dall'esterno verso l’interno, di una serie di avvenimenti attraverso i quali pren…
MULTIRESOLUTION ANALYSIS FOR IRREGULAR MESHES WITH APPEARANCE ATTRIBUTES
2004
We present a new multiresolution analysis framework based on the lifting scheme for irregular meshes with attributes. We introduce a surface prediction opera- tor to compute the detail coefficients for the geometry and the attributes of the model. Attribute analysis gives appearance information to complete the geomet- rical analysis of the model.We present an application to adaptive visualization and some experimental results to show the efficiency of our framework.
Entire reflective object surface structure understanding based on reflection motion estimation
2015
An sub-segmentation method for the reflective surface structure understanding.The use of reflection motion features as spatiotemporal coherence for video segmentation.Straightforward implementation.A building block for object recognition. The presence of reflection on a surface has been a long-standing problem for object recognition since it brings negative effects on object's color, texture and structural information. Because of that, it is not a trivial task to recognize the surface structure affected by the reflection, especially when the object is entirely reflective. Most of the cases, reflection is considered as noise. In this paper, we propose a novel method for entire reflective obj…
Visual Discrimination of the 17 Plane Symmetry Groups
2011
Within most of the 17 plane symmetry groups, individual symmetry operations act in multiple, nonequivalent ways. This, and the fact that many groups can be realized on the basis of different unit cells and generating regions, poses difficulties for visual discrimination and identification. Because of inherent confounds, only few of the groups can be studied by traditional experimental methodology. The use of an oddity paradigm and specific tiling patterns that camouflage groups in complex textures are recommended as partial remedy to this impasse. In order to prepare readers for an appreciation of the aforementioned issues and to provide a rationale for their investigation, the reporting of…
