Fundamentals of automated human gesture recognition using 3D integral imaging: a tutorial
2020
Automated human gesture recognition is receiving significant research interest, with applications ranging from novel acquisition techniques to algorithms, data processing, and classification methodologies. This tutorial presents an overview of the fundamental components and basics of the current 3D optical image acquisition technologies for gesture recognition, including the most promising algorithms. Experimental results illustrate some examples of 3D integral imaging, which are compared to conventional 2D optical imaging. Examples of classifying human gestures under normal and degraded conditions, such as low illumination and the presence of partial occlusions, are provided. This tutorial…
Multidimensional Integral Imaging for Sensing, Visualization, and Recognition in Degraded Environments
2019
An overview of multidimensional integral imaging for sensing, visualization, and recognition in degraded environments is presented. Applications include 3D visualization, photon starved imaging, material inspection, IR imaging, passive depth estimation, automated human gesture recognition, and long-range imaging.
Parlare per ascoltarsi. Note su alcuni aspetti dell'interlocuzione.
2015
This paper considers the nature of interlocution from the point of view of three different research programs: the theory of enunciative operations of Antoine Culioli (or toe), the psychoanalysis of Jacques Lacan (or pla) and the enactive grammar of Didier Bottineau (or ge). It is composed of three parts: in the first part, we introduce some definitions of interlocution in order to distinguish between terms and empirical supports of interlocution. The second part is devoted to the analysis of some sensorial operations that are at work in the context of verbal inter- action – with particular reference to the cases of acoustic feedback. Finally, in the last part we discuss in which sense and u…
Fragmentos de um discurso político. Intervenções críticas
2019
This essay argues for the pertinence of the semiotic view on politics, as well as the political character of research in semiotics. Through about the discursive organization in contemporary politics, and the idea of political discourse, the author elaborates analyses and reflections on themes and passions with which he identifies a specific way for semiotics to answer the questions promoted by the field of politics. To this end, the author elaborates analyses and reflections on themes and passions with which he identifies a specific way for semiotics to answer the questions promoted by the field of politics. The work also aims to deconstruct myths and naturalized meanings. Such semiotic ges…
Arturo Toscanini
2018
Thanks to the new media, i.e., record, radio and TV, Arturo Toscanini was the first conductor known by every kind of public in the world. The essay examines Toscanini’s art of conducting in five crucial issues. The foundation of a supranational repertoire of orchestral music enclosing ancient, modern and contemporaneous authors (from Corelli to Strawinsky). The reform of opera house and the paths of maestro in re-thinking the Italian opera after a deep study of Richard Wagner’s Musikdrama. The impressive use of memory in view of a close control of the orchestra (he conducted by heart over 600 scores). The personal, inelegant but effective gesture, by which Toscanini fascinated orchestras in…
Proximal and distal. Rethinking linguistic form and use for clinical purposes.
2010
With clinical purposes in mind, a review of the proximal/distal opposition is carried out in order to define a universal parameter of variability in semiotic procedures. By taking into consideration different-although notionally inter-related-senses of the proximal/distal opposition, a cluster of semiotic properties is proposed, which initially permits one to characterize dimensions of variability in the form and use of gestures. The subsequent and central aim of this paper is, however, to demonstrate that the same, or homologous, properties can also serve to characterize variability in the use of language, by assuming a basic connection between gesturing and linguistic behaviour. The main …
The Marginalisation of Finely Tuned Semiotic Practices and Misunderstandings in Relation to (Signed) Languages and Deafness
2014
AbstractWhen people draw on the available modal resources (e.g. gestures) in specific contexts over time, those resources come to display regularities. The more a community uses and regulates those resources, the more fully and finely articulated their regularities and patterns become. Modes, organised by regular means of representation, are constantly transformed by users, depending on what the community needs. This paper discusses the way semiotic resources and practices, i.e. social actions with a history, used by sign language signers in visually oriented communities, as well as the research in such domains, have been marginalised. The paper reflects some of the main reasons for such ma…
Early communicative gestures and play as predictors of language development in children born with and without family risk for dyslexia
2014
The present study investigated early communicative gestures, play, and language skills in children born with family risk for dyslexia (FR) and a control group of children without this inheritable risk at ages 12, 15, 18, and 24 months. Participants were drawn from the Tromsø Longitudinal study of Dyslexia (TLD) which follows children's cognitive and language development from age 12 months through Grade 2 in order to identify early markers of developmental dyslexia. Results showed that symbolic play and parent reported play at age 12 months and communicative gestures at age 15 months explained 61% of the variance in productive language at 24 months in the FR group. These early nonlinguistic …
Feeling addressed! The neural processing of social communicative cues in patients with major depression
2020
Abstract The feeling of being addressed is the first step in a complex processing stream enabling successful social communication. Social impairments are a relevant characteristic of patients with major depressive disorder (MDD). Here, we investigated a mechanism which—if impaired—might contribute to withdrawal or isolation in MDD, namely, the neural processing of social cues such as body orientation and gesture. During funtional magnetic resonance imaging (fMRI) data acquisition, 33 patients with MDD and 43 healthy control subjects watched video clips of a speaking actor: one version with a gesture accompanying the speech and one without gesture. Videos were filmed simultaneously from two …
Ball Impact Position in Recreational Male Padel Players: Implications for Training and Injury Management
2021
Racket sports such as padel are characterized by the repetition of unilateral gestures, which can lead to negative adaptations like asymmetries or overuse musculoskeletal injuries. The purpose of this study was to determine the differences in ball impact positions (i.e., forward or backward of the center of gravity) in nine stroke types in a sample of forty-eight recreational male padel players. The sample included 14,478 shots corresponding to 18 matches from six tournaments. Forty-eight male padel players were classified into two groups according to their level: trained (n = 24) and novice (n = 24). Type of stroke and ball impact position were registered using a computerized motion tracki…
