HDR-­ARtiSt: a FPGA-­based Smart Camera for High Dynamic Range color video from multiple exposures

2014

International audience; A camera is able to capture only a part of a high dynamic range scene information. The same scene can be fully perceived by the human visual system. This is true especially for real scenes where the difference in light intensity between the dark areas and bright areas is high. The imaging technique which can overcome this problem is called HDR (High Dynamic Range). It produces images from a set of multiple LDR images (Low Dynamic Range), captured with different exposure times. This technique appears as one of the most appropriate and a cheap solution to enhance the dynamic range of captured environments. We developed an FPGA-based smart camera that produces a HDR liv…

UNE APPROCHE PARALLELE D'EVALUATION DES PARAMETRES DE TEXTURE POUR L'ANALYSE D'IMAGES DE GRANDE TAILLE

2011

International audience; The main objective of this paper is to develop a new image processing technique that could better be adapted to the processing of large and complex images, especially SAR images, in relation to the former methods of our works. We propose here a new approach of textural parameters evaluation which is about (Ng+1)n-1 times faster than the co-occurrence matrix approach considered as classical, where n is the order of the textural parameter and Ng being the maximum grey level in the image. This approach is based on a new modeling of textural parameters of a generic order n>1 equivalent to the classical formulation, but which is no longer based on frequency matrix (co-occ…

ADI schemes for valuing European options under the Bates model

2018

This paper is concerned with the adaptation of alternating direction implicit (ADI) time discretization schemes for the numerical solution of partial integro-differential equations (PIDEs) with application to the Bates model in finance. Three different adaptations are formulated and their (von Neumann) stability is analyzed. Ample numerical experiments are provided for the Bates PIDE, illustrating the actual stability and convergence behaviour of the three adaptations. peerReviewed

Roll-with-Participation. Il caso di ProMondello a Palermo

2018

This contribution is based on an ongoing experience in Palermo: a participatory process (ProMondello) aimed at producing a master plan. The specificity of ProMondello stems from the fact that the promoters of the process are neither social communities nor local administrations, which so far have only arranged highly questionable and easily exploitable processes. ProMondello is organised by a private stakeholder, the Italo-Belgian Real Estate Company, which has been managing a beach concession for about a century. The case raises several questions: can we have true participation along with such obvious economic interests? What can ensure that citizens’ opinions are not instrumentally used? T…

Implementation of participatory sensing approach in mobile vehicle based sensor networks

2013

In this paper author describes his research with the goal to develop and experimentally verify specific data recording and processing methodologies based on participatory sensing approach implementation in mobile vehicle based sensor networks. To reach this goal, author performed study of literature, testing of hypothesis using general purpose computer devices, adaptation of smartphones for participatory sensing, development of special purpose embedded devices, practical experiments with selected technical equipment and software as well as gathering of experimental results and following statistical analysis. The result of this research are several data acquisition and processing methodologi…

Image classification based on 2D feature motifs

2013

The classification of raw data often involves the problem of selecting the appropriate set of features to represent the input data. In general, various features can be extracted from the input dataset, but only some of them are actually relevant for the classification process. Since relevant features are often unknown in real-world problems, many candidate features are usually introduced. This degrades both the speed and the predictive accuracy of the classifier due to the presence of redundancy in the candidate feature set. In this paper, we study the capability of a special class of motifs previously introduced in the literature, i.e. 2D irredundant motifs, when they are exploited as feat…

Overview of development lines of music teaching methods in Finland

2020

This article provides a cross-sectional overview of the evolution of music teaching methods over a 160-year timeline. The objective of the study is limited to examining the mainstream trends in the development of methods, or their manifestations, as well as discussing the causes behind them. The objective is also to investigate the methodical state of the 21st century teaching. The data consists of previous studies, music textbooks and learning diaries of class teacher students (N=79). The analysis of the data is based on analytic-historical and data-driven content analysis. The time period from 1860 to1970 has focused on developing the methods. The participatory and functional methods have…

Badanie i działanie w obszarze poznania społeczno-pedagogicznego. Tradycja pedagogiki społecznej Heleny Radlińskiej

2018

Pedagogika społeczna jest nauką praktyczną. Założycielką tej nauki w Polsce jest Helena Radlińska. Poznanie naukowe badanej rzeczywistości służy przetwarzaniu warunków życia osób, rodzin i grup społecznych. W tradycji badań społeczno-pedagogicznych badanie łączy się ściśle z działaniem. Podkreślała to H. Radlińska w założeniach metodologicznych pedagogiki społecznej. W toku edukacji pedagogów społecznych istotnym elementem jest kształtowanie kompetencji badawczych. Są one ważnym składnikiem przygotowania do służby społecznej, oświatowej, wychowawczej oraz kulturalnej

The inspiration in improvisation : identifying and classifying the approaches to emotion-based musical improvisation

2016

The purpose of this study was to identify the naturally occurring approaches that musicians use to improvise and to analyse the relationships between the approach used, the improviser’s musical experience, and the quality of the resulting improvisation. 16 participants took part in three group improvisation and discussion sessions, and the improvisations of the final session (80 in total) were recorded and rated by experts on emotions- and quality-related aspects. The approaches mentioned by participants in the final session were organised into five distinct categories: technical, musical inspiration, nuanced emotion, visualized scene, and personal experience. Significant negative correlati…
