A Data Association Algorithm for People Re-Identification in Photo Sequences

2010

In this paper, a new system is presented to support the user in the face annotation task. Every time a photo sequence becomes available, the system analyses it to detect and cluster faces in set corresponding to the same person. We propose to model the problem of people re-identification in photos as a data association problem. In this way, the system takes advantage from the assumption that each person can appear at most once in each photo. We propose a fully automated method for grouping facial images, the method does not require any initialization neither a priori knowledge of the number of persons that are in the photo sequence. We compare the results obtained with our method and with s…

Genealogie dell'empatia. Brecht, Lessing e Stanislavskij

2018

Sulla base di concetti quali empatia, compassione e immedesimazione, il lavoro mette a confronto le teorie estetiche di Brecht, Lessing e Stanislavskij. Ricostruendo le tappe del fecondo rapporto di scambio dialettico che lega il drammaturgo tedesco del '900 all'attore e regista russo e al drammaturgo teorico della drammaturgia della compassione del 700, si analizza un caso di tormentata ricezione. Based on concepts such as empathy, compassion and identification, the work compares the aesthetic theories of Brecht, Lessing and Stanislavsky.

L’importanza dei prerequisiti e dello screening precoce nella scuola dell’infanzia

2016

Questo contributo si propone di sottolineare l’importanza di alcune competenze cognitive, detti prerequisiti, che sono implicate nell’acquisizione delle abilità di lettura e scrittura come ad esempio: la conoscenza dell’alfabeto; la consapevolezza fonologica; la denominazione rapida automatica (RAN); la memoria fonologica e la processazione visiva. Numerose ricerche, anche internazionali, mostrano l’importanza dell’esercizio di tali abilità all’interno della scuola dell’infanzia anche ai fini della prevenzione dello sviluppo di difficoltà di apprendimento e/o di veri e propri disturbi nella successiva carriera accademica del bambino. Inoltre, la realizzazione di interventi didattici mirati …

Socio-developmental aspects of European identity: The influence of age, gender and context

2010

In the last years, researchers have been interested in understanding factors affecting the development of European identity. To contribute new insights to the literature, this study explored how age, gender and context variables influence the process of European identification and the attitudes towards Europeans in two different Italian groups: Northern Italians and Southern Italians. Interview data were collected from 1037 children and adolescents (472 males, 565 females), aged from 6 to 16 years old and living in northern and southern regions of Italy. They were asked to answer an individual interview during school time. For the particular purposes of the study, four main measures were us…

Incipient damage identification through characteristics of the analytical signal response

2008

The analytical signal is a complex representation of a time domain signal: the real part is the time domain signal itself, while the imaginary part is its Hilbert transform. It has been observed that damage, even at a very low level, yields clearly detectable variations of analytical signal quantities such as phase and instantaneous frequency. This observation can represent a step toward a quick and effective tool to recognize the presence of incipient damage where other frequency-based techniques fail. In this paper a damage identification procedure based on an adimensional functional of the square of the difference between the characteristics of the analytical theoretical and measured sig…

Improving similarity measures for re-identification of vehicles using AMR sensors

2013

The use of Anisotropic Magneto-Resistive (AMR) sensors for road traffic monitoring has gained popularity in recent years. The Earth magnetic field variations caused by vehicles passing over this kind of sensors can be measured and used for various purposes, including vehicle re-identification at different sensing zones. AMR sensors provide data that allow the calculation of traffic parameters by using simple signal processing techniques. But when vehicle re-identification is the objective, it is not clear which is the best method to compare the signals from different sensors in order to know whether or not they belong to the same vehicle. This paper presents an experimental study with the o…

Support Vector Machines Framework for Linear Signal Processing

2005

This paper presents a support vector machines (SVM) framework to deal with linear signal processing (LSP) problems. The approach relies on three basic steps for model building: (1) identifying the suitable base of the Hilbert signal space in the model, (2) using a robust cost function, and (3) minimizing a constrained, regularized functional by means of the method of Lagrange multipliers. Recently, autoregressive moving average (ARMA) system identification and non-parametric spectral analysis have been formulated under this framework. The generalized, yet simple, formulation of SVM LSP problems is particularized here for three different issues: parametric spectral estimation, stability of I…

Leaders’ Style, Self-Sacrifice, and Team Identification

2013

Leadership is a group feature that directly impacts on team identification. Effective leaders are especially capable of fostering group cohesiveness and promoting efficacy in goal attainment. We assessed the relationship between transactional and transformational leadership style, team identification, and leader self-sacrifice. Participants were 186 call center employees who were headed by a leader who operated with either a transactional or a transformational leadership style. The employees reported their level of team identification and leader self-sacrifice. Results show how, in either the transactional or transformational leadership condition, levels of leadership and self-sacrifice wer…

Social comparison processes, narrative mapping and their shaping of the cancer experience: a case study of an elite athlete.

2011

Drawing on data generated by life history interviews and fieldwork observations we illuminate the ways in which a young elite athlete named David (a pseudonym) gave meaning to his experiences of cancer that eventually led to his death. Central to this process were the ways in which David utilized both social comparisons and a narrative map provided by the published autobiography of Lance Armstrong (2000). Our analysis reveals the selective manner in which social comparison processes operated around the following key dimensions: mental attitude to treatment; the sporting body; the ageing body; and physical appearance. The manner in which different comparison targets were chosen, the ways in…
