Reliable Planar Object Pose Estimation in Light Fields From Best Subaperture Camera Pairs

2018

International audience; A light-field camera can obtain richer information about a scene than a usual camera. This property offers a lot of potential for robot vision. In this paper, we present a method for pose estimation of a planar object with a light-field camera. The light-field camera can be regarded as a set of sub-aperture cameras. Although any combination of them can theoretically be used for the pose estimation, the accuracy depends on the combination. We show that the estimated pose error can be reduced by selecting the best pair of sub-aperture cameras. We have evaluated the accuracy of our approach with real experiments using a light-field camera in front of planar targets held…

Onset of Convection in an Inclined Anisotropic Porous Layer with Internal Heat Generation

2019

The onset of convection in an inclined porous layer which is heated internally by a uniform distribution of heat sources is considered. We investigate the combined effects of inclination, anisotropy and internal heat generation on the linear instability of the basic parallel flow. When the Rayleigh number is sufficiently large, instability occurs and a convective motion is set up. It turns out that the preferred motion at convection onset depends quite strongly on the anisotropy ratio, &xi

Compact, cost-effective and field-portable microscope prototype based on MISHELF microscopy

2016

AbstractWe report on a reduced cost, portable and compact prototype design of lensless holographic microscope with an illumination/detection scheme based on wavelength multiplexing, working with single hologram acquisition and using a fast convergence algorithm for image processing. All together, MISHELF (initials coming from Multi-Illumination Single-Holographic-Exposure Lensless Fresnel) microscopy allows the recording of three Fresnel domain diffraction patterns in a single camera snap-shot incoming from illuminating the sample with three coherent lights at once. Previous implementations have proposed an illumination/detection procedure based on a tuned (illumination wavelengths centered…

Spatially-multiplexed interferometric microscopy (SMIM): converting a standard microscope into a holographic one

2014

We report on an extremely simple, low cost and highly stable way to convert a standard microscope into a holographic one. The proposed architecture is based on a common-path interferometric layout where the input plane is spatially-multiplexed to allow reference beam transmission in a common light-path with the imaging branch. As consequence, the field of view provided by the layout is reduced. The use of coherent illumination (instead of the broadband one included in the microscope) and a properly placed one-dimensional diffraction grating (needed for the holographic recording) complete the experimental layout. The proposed update is experimentally validated in a regular Olympus BX-60 upri…

Learning as Issue Framing in Agricultural Innovation Networks

2014

AbstractPurposeNetworks are increasingly viewed as entities of learning and innovation in agriculture. In this article we explore learning as issue framing in two agricultural innovation networks.Design/methodology/approachWe combine frame analysis and social learning theories to analyse the processes and factors contributing to frame convergence and hence improved practical collaborative outcomes in networks. Issue framing in the networks was followed during a two-year period with the help of multiple methods assembled under a transdisciplinary case study, action research and grounded methodology framework.FindingsOur research suggests that learning and collective action for more sustainab…

Collaborative 3D learning games for future learning: teachers’ instructional practices to enhance shared knowledge construction among students

2013

Collaborative games will enable new kinds of possibilities for learning. In the future, the goal of game-based learning should be to introduce new ideas and deepen in-depth understanding of learners. However, studies have shown that shared high-level knowledge construction is a challenging process. Moreover, thus far, few empirical studies have examined what constitutes the teacher’s role in games. The focus of this paper is to investigate teachers’ real-time instructional activities in a scripted 3D game setting. Our hypothesis is that groups with real-time teacher instruction will come up with more shared knowledge construction that can be considered productive than groups studying withou…

Differences in Technical Development and Playing Space in Three UEFA Champions Leagues

2021

[Abstract] The analysis of football grows exponentially, with many researchers adopting it as an object of study. The thematic range that addresses it, as well as the different methodologies used, are of a very different nature—physical, psychological, technical, tactical—enriching every day the knowledge, and understanding of the game itself. The objective of this study has been to identify the differences between the different styles of play that lead to becoming the champion of the UEFA Champions League in the last 3 years of the pre-COVID stage, by analyzing the spatial performance developed, the association between the players that make up the different lines of the game system and the…

Implementing Digital Government in the Finnish Parliament

2005

The Finnish Parliament has been active in utilizing information and communication technologies in the parliamentary work as well as in communicating with citizens and other organizations. As common in public sectors, work, knowledge management, and communication in the environment is document-centric. A strategic issue in implementing digital government has been SGML/XML standardization. The Finnish Parliament has been a pioneer in the adoption of SGML/XML technologies. The chapter reports experiences from the standardization efforts. The implications of the standardization will be examined from the viewpoints of documents, information technology, work with documents, the Finnish Parliament…

COLTIVAZIONE DI PIANTE OFFICINALI ANNUALI DA SEME CON TECNICHE ECOCOMPATIBILI

2009

La Sicilia, caratterizzata da un’ampia variabilità pedo-climatica e da una notevole ricchezza di paesaggi naturali e tradizioni popolari, è sede ideale per la valorizzazione delle risorse vegetali di interesse officinale spontanee o spontaneizzate nell’area mediterranea, da introdurre o diffondere in coltivazione. Sulla base di questa premessa, allo scopo di valorizzare alcune specie officinali mediterranee, è stata condotta una sperimentazione pluriennale, che ha riguardato la coltivazione in pieno campo di tali specie, con tecniche ecocompatibili. Scopo della ricerca è stato quindi la messa a punto dei principali aspetti dell’agrotecnica applicabile ad alcune specie officinali di possibil…
