Fusion of multimodal data by combining the uncertainty and perception models

2019

The general idea is to use together heterogeneous multiple information on the same problem tainted by imperfections and coming from several sources in order to improve the knowledge of a given situation. Appropriate visualization of the images to aid in decision making using the perceptual information carried by the salience maps.

QUANDO IL GESTO SI FA LINGUA

2012

Gesto e vocalità formano una complessa unità significativa su cui si basano le operazioni fondamentali dell'attività di linguaggio. Nel saggio, esamino alcuni aspetti di questa unità alla luce di alcune categorie metalinguistiche introdotte nel contesto delle teorie dell'enunciazione

Transmediating argumentation : Students composing across written essays and digital videos in higher education

2016

This comparative study examined how university students built an argument in written essays and multimodal digital videos, and how their argumentation transmediated across these two mediums. Data analysis involved 1) analysis of content in both written essays and digital videos; 2) the development of transmediation visualizations to elucidate how ideas were transformed from essays into videos; and 3) multimodal analysis to understand the communicative affordances and constrains for argumentation with each medium. The findings revealed that the most common type of content in both essays and videos was supportive argumentation; however, the videos did not include any counter-argumentation. St…

Mathematical logic and quantum finite state automata

2009

AbstractThis paper is a review of the connection between formulas of logic and quantum finite-state automata in respect to the language recognition and acceptance probability of quantum finite-state automata. As is well known, logic has had a great impact on classical computation, it is promising to study the relation between quantum finite-state automata and mathematical logic. After a brief introduction to the connection between classical computation and logic, the required background of the logic and quantum finite-state automata is provided and the results of the connection between quantum finite-state automata and logic are presented.

Study of new tellurite glasses in the TeO2-ZnO-La2O3 (TZL) system for the manufacturing of mid-infrared multimaterial optical fibers and specialty op…

2023

This thesis work was carried out using tellurite glasses from the TeO2-ZnO-La2O3 (TZL) ternary diagram for optical fibers manufacturing. The choice to use this system is motivated by the ambition to improve the transmission of optical signals within oxide glasses for which absorption bands related to OH groups are present in the transparency window. A structural study is first carried out on these glasses by Raman spectroscopy in order to understand the influence of the composition on physicochemical properties (especially on optical and thermal properties) but also to estimate the ability of a vitreous matrix to reorganize when subjected to a thermal solicitation such as the preform-to-fib…

Improving point matching on multimodal images using distance and orientation automatic filtering

2016

International audience; Speed Up Robust Features SURF is one of the most popular and efficient methods used for image registration task. In order to achieve a correct registration, a good matching of feature point is required. However in the case of multimodal images, the high and non-linear intensity changes between different modalities led to many outliers (mismatching of detected points) and consequently a fail in the registration. Therefore, in this paper we introduce an efficient method devoted to the detection and removal of such outlier. It's based on an automatic filtering of outliers on both distance and orientation between features points. We tested our proposed method on a set of…

Diagnostic performance and reproducibility of T2w based and diffusion weighted imaging (DWI) based PI-RADSv2 lexicon descriptors for prostate MRI.

2017

To examine the diagnostic performance of PI-RADSv2 T2w and diffusion weighted imaging (DWI) based lexicon descriptors, inter-observer agreement for descriptor assignment and diagnostic accuracy of the PI-RADSv2 assessment categories for multiparametric prostate MRI.176 lesions in 79 consecutive patients are analyzed, lesions are histopathologically verified by MRI-ultrasound fusion biopsy. All lesions are rated according to the PI-RADSv2 lexicon, descriptors for T2w and DWI sequences and resulting assessment categories are assigned by two independent blinded radiologists. We perform receiver-operating-characteristic analysis using the assessment categories. To analyze inter-observer agreeme…

Synthesis and study of new fluorescent probes for optical imaging, Cherenkov imaging and multimodal imaging

2015

The goal of this work was to prepare and study new fluorescent probes, which could give rise to novel optical or Cherenkov imaging agents. The first section of this work describes the synthesis of fluorescent subphthalocyanines and phthalocyanines probes, which possess relevant chemicals groups suitable for optical imaging applications. The optical and physico-chemical properties of the new probes were carefully examined to ensure they comply with the specification of the fluorophores for the desired application. The second part focused on the subsequent development of a few selected probes into real imaging agents. The biovectorisation of subphtalocyanines was achieved upon conjugation of …

University Students as Composers of a Digital Video

2013

This paper introduces a university course in which digital video composing was used as a study method. The aim of the course was to empower future teachers to use digital and multimodal literacy practices in their own teaching. Students in education, 13 in total, participated in the course on digital literacies. The course achievement was measured with the task in which students composed a video in small-groups. The students’ videos were supposed to convince a pedagogical target group about the usefulness of a teaching method or need for a reform. In the last meeting, student’s videos were watched and the contents of the videos were discussed. The experiences on composing a digital video we…
