    L'histoire du cinĂ©ma 3D est presque aussi longue que celle du cinĂ©ma 2D. Toutefois, ce n'est qu'avec l'utilisation des mĂ©dias numĂ©riques que la commercialisation du contenu stĂ©rĂ©oscopique 3D s'est concrĂ©tisĂ©e. Puisque la production stĂ©rĂ©oscopique 3D nĂ©cessite l'utilisation de deux camĂ©ras, il est nĂ©cessaire de correctement ajuster celles-ci afin de produire du contenu pouvant ĂȘtre visualisĂ© sans inconfort, tout en reproduisant adĂ©quatement les caractĂ©ristiques du systĂšme visuel humain permettant la perception en profondeur. Les outils d'assistance Ă  l'ajustement des camĂ©ras stĂ©rĂ©oscopiques Ă©tant coĂ»teux, la production de contenu stĂ©rĂ©oscopique est gĂ©nĂ©ralement rĂ©servĂ©e aux utilisateurs expĂ©rimentĂ©s ou ayant des moyens financiers suffisants. Afin de rendre disponible l'utilisation et l'amĂ©lioration de cette technologie, il serait pertinent de fournir des outils gratuits et libres de droit. Puisqu'il existe des bibliothĂšques logicielles libres pour le traitement d'images stĂ©rĂ©oscopiques appliquĂ© au domaine de la reconstruction 3D, ce projet cherche Ă  Ă©valuer la possibilitĂ© d'adapter ces algorithmes pour le dĂ©veloppement d'outils logiciels temps rĂ©el d'assistance Ă  la production de contenu stĂ©rĂ©oscopique. Pour ce faire, la dĂ©tection et la correspondance de points caractĂ©ristiques sont utilisĂ©s afin de dĂ©terminer l'alignement relatif des camĂ©ras par l'estimation de la gĂ©omĂ©trie Ă©pipolaire. Les problĂšmes d'alignement sont par la suite corrigĂ©s par la rectification numĂ©rique des images. Afin d'obtenir une rectification stable en temps rĂ©el, les rĂ©sultats montrent que des amĂ©liorations doivent ĂȘtre apportĂ©es aux algorithmes d'alignement et de rectification des images: 1) l'utilisation d'un dĂ©tecteur de points caractĂ©ristiques alternatif non-propriĂ©taire permettrait une meilleure performance; 2) l'utilisation d'un algorithme alternatif pour l'estimation robuste de l'alignement des camĂ©ras permettrait une estimation sans avoir Ă  dĂ©terminer de paramĂštres de façon empirique; 3) l'utilisation d'un filtre de Kalman serait nĂ©cessaire pour une rectification stable des images lors d'une sĂ©quence vidĂ©o. Le projet vise Ă  l'intĂ©gration des techniques et de leurs amĂ©liorations dans une bibliothĂšque logicielle Ă  code source ouvert, OpenS3D. Les fonctionnalitĂ©s intĂ©grĂ©es dans OpenS3D sont la visualisation de contenu stĂ©rĂ©oscopique, les calculs pour l'assistance Ă  l'alignement des camĂ©ras, la rectification numĂ©rique des images, l'analyse des profondeurs perçues pour une scĂšne capturĂ©e. Toutes les fonctionnalitĂ©s sont disponibles en temps rĂ©el Ă  partir de l'interface utilisateur d'OpenS3D. Puisque les amĂ©liorations apportĂ©es aux techniques de calcul d'alignement des camĂ©ras permettent d'obtenir une estimation stable et cohĂ©rente au niveau temporel, cette estimation pourrait ĂȘtre directement utilisĂ©e afin de corriger les erreurs d’alignement de façon automatique. Une automatisation des paramĂštres des camĂ©ras permettrait par exemple de filmer des scĂšnes 3D Ă  partir de robots mobiles. De plus, des techniques supplĂ©mentaires pourraient ĂȘtre ajoutĂ©es au logiciel telles que l'analyse de rivalitĂ©s rĂ©tiniennes pour les diffĂ©rences de couleur, de luminositĂ© ou de reflets lumineux

    Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)

    In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. For example, a key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process versus those that measure fl ux through the autophagy pathway (i.e., the complete process including the amount and rate of cargo sequestered and degraded). In particular, a block in macroautophagy that results in autophagosome accumulation must be differentiated from stimuli that increase autophagic activity, defi ned as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (inmost higher eukaryotes and some protists such as Dictyostelium ) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the fi eld understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. It is worth emphasizing here that lysosomal digestion is a stage of autophagy and evaluating its competence is a crucial part of the evaluation of autophagic flux, or complete autophagy. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. Along these lines, because of the potential for pleiotropic effects due to blocking autophagy through genetic manipulation it is imperative to delete or knock down more than one autophagy-related gene. In addition, some individual Atg proteins, or groups of proteins, are involved in other cellular pathways so not all Atg proteins can be used as a specific marker for an autophagic process. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field

    ARIA digital anamorphosis: Digital transformation of health and care in airway diseases from research to practice

    Get PDF
    Digital anamorphosis is used to define a distorted image of health and care that may be viewed correctly using digital tools and strategies. MASK digital anamorphosis represents the process used by MASK to develop the digital transformation of health and care in rhinitis. It strengthens the ARIA change management strategy in the prevention and management of airway disease. The MASK strategy is based on validated digital tools. Using the MASK digital tool and the CARAT online enhanced clinical framework, solutions for practical steps of digital enhancement of care are proposed
