Mixed Reality Annotation of Robotic-Assisted Surgery videos with real- time tracking and stereo matching
2023
Robotic-Assisted Surgery (RAS) is beginning to unlock its potential. However, despite the latest advances in RAS, the steep learning curve of RAS devices remains a problem. A common teaching resource in surgery is the use of videos of previous procedures, which in RAS are almost always stereoscopic. It is important to be able to add virtual annotations onto these videos so that certain elements of the surgical process are tracked and highlighted during the teaching session. Including virtual annotations in stereoscopic videos turns them into Mixed Reality (MR) experiences, in which tissues, tools and procedures are better observed. However, an MR-based annotation of objects requires trackin…
<title>Combining multiple image descriptions for browsing and retrieval</title>
2000
Retrieving images form large collections using image content is an important problem, in this multimedia age. A quick content-based visual access to the stored image is capital for efficient navigation through image collections. In this paper we introduce several techniques which characterize color homogeneous object and their spatial relationships for efficient content-based image retrieval. We present a region growing technique for efficient color homogeneous objects segmentation and extend the 2D string to an accurate description of spatial information and relationships. In order to improve content-based image retrieval, our method emphasized several objectives, such as: automated extrac…
Automatic building of a visual interface for content-based multiresolution retrieval of paleontology images
2001
In this article we present research work in the field of content-based image retrieval in large databases applied to the paleontology image database of the Universite´ de Bourgogne, Dijon, France, called ‘‘TRANS’TYFIPAL.’’ Our indexing method is based on multiresolution decomposition of database images using wavelets. For each family of paleontology images we try to find a model image that represents it. The K-means automatic classification algorithm divides the space of parameters into several clusters. A model image for each cluster is computed from the wavelet transform of each image of the cluster. Then a search tree is built to offer users a graphic interface for retrieving images. So …
Il disegno del movimento
2019
Nel tempo, il gesto, lo spazio, il suono, immaginati come involucri del pensare, hanno preso forma attraverso sistemi notazionali “rendendo presente”, “rappresentando” la traccia, altrimenti invisibile, del moto corporeo nello spazio. Il saggio approfondisce le questioni grafiche relative alle modalità di espressione del gesto a partire dalla notazione Laban, meglio nota come Labanotation, per comprendere le operazioni di osservazione e registrazione del movimento attraverso il codice del Disegno, tenendo conto delle implicazioni percettive sulla costruzione gestuale nella dimensione visuale. Over time, the gesture, the space, the sound, imagined as envelopes of thought, have taken shape th…
Atomic scale DFT simulations of point defects in uranium nitride
2007
Atomic scale density functional calculations are used to predict the behaviour of defects in uranium mononitride (UN). Two different density functional codes (VASP and CASTEP) were employed with supercells containing from 8 to 250 atoms (providing a significant range of defect concentrations). Schottky and nitrogen Frenkel point defect formation energies, local lattice relaxations and overall lattice parameter change, as well as the defect induced electronic density redistribution, are discussed.
Designing the Didactic Strategy Modeling Language (DSML) From PoN: An Activity Oriented EML Proposal
2018
[EN] This paper presents the design of the didactic strategy modeling language (DSML) according to the principles of Physics of Notations (PoN). The DSML is a visual and activity-oriented language for learning design characterized by the representation of different activities according to the nature of the task. Once the language is designed, a blind interpretation study is conducted to validate the semantic transparency of the learning activity iconography. The results of the paper allow to refine the icons. In addition to this, an authoring tool for DSML, which is integrated to an LMS, is presented. As a result, a model driven course was designed as a DSML pre-validation.
Hybrid sequencing approach applied to human fecal metagenomic clone libraries revealed clones with potential biotechnological applications.
2012
Natural environments represent an incredible source of microbial genetic diversity. Discovery of novel biomolecules involves biotechnological methods that often require the design and implementation of biochemical assays to screen clone libraries. However, when an assay is applied to thousands of clones, one may eventually end up with very few positive clones which, in most of the cases, have to be "domesticated" for downstream characterization and application, and this makes screening both laborious and expensive. The negative clones, which are not considered by the selected assay, may also have biotechnological potential; however, unfortunately they would remain unexplored. Knowledge of t…
"Lavorare" il dato linguistico: prospettive e limiti. Alcune considerazioni dall'esperienza dell'Atlante Linguistico della Sicilia (ALS)
2018
The present work focuses on the relationship between linguistic research and the use of new technologies for linguistic data processing and analysis. Starting from the experience of the Atlante Linguistico della Sicilia (ALS), this paper describes a XML schema, based on the theory of trasferenza (transference) by Regis (2013), for the annotation and analysis of the data from the onomasiological questions of the ALS sociovariational questionnaire. Moreover, this modest case study tries to make clear the pros and cons of technological devices in linguistic research.
Les eines computacionals i el disseny de corpus orals: un diàleg vigent
2020
The design of an oral corpus and the processes of registering, codifying and treating the materials in order to build a useful resource for linguistic analysis prompt numerous decisions regarding theory and methodology. This article is focused on those stages of corpus construction which are more clearly conditioned by the computational processing necessary to make it functional. In order to adequately match the initial expectations and the real possibilities of using the tool, each feature we intend to codify must be measured against the workload and the means required to do so. Therefore, it is essential to take into account the available possibilities of processing and exploitation as th…
The changing schoolscape in a Szekler village in Romania: signs of diversity in rehungarization
2015
In this paper, we explore the connections between a linguistic landscape and language ideologies in an elementary school in a village within the Hungarian region of Szeklerland in Romania. This ‘schoolscape’ is analysed as a display or materialization of the ‘hidden curriculum’ regarding the construction of linguistic and cultural identities. We draw on fieldwork carried out in 2012 and 2013 and examine two dimensions of change in progress: (1) changes in the use of Hungarian and Romanian as languages of teaching and learning and as languages of written administration; and (2) changes in the display of these languages in the schoolscape. Since 1990, there has been a tendency towards rehunga…
