Cost-driven framework for progressive compression of textured meshes

2019

International audience; Recent advances in digitization of geometry and radiometry generate in routine massive amounts of surface meshes with texture or color attributes. This large amount of data can be compressed using a progressive approach which provides at decoding low complexity levels of details (LoDs) that are continuously refined until retrieving the original model. The goal of such a progressive mesh compression algorithm is to improve the overall quality of the transmission for the user, by optimizing the rate-distortion trade-off. In this paper, we introduce a novel meaningful measure for the cost of a progressive transmission of a textured mesh by observing that the rate-distor…

In-mouth aroma compound release during cheese consumption: Relationship with food bolus formation

2011

International audience; The present study describes the changes in mechanical properties and saliva incorporation for cheese samples with different composition and texture, and their influence on the rate of aroma release. Chewing work per cycle, salivary flow rate and chewing rate varied highly among subjects. Despite the differences in cheese hardness, at the end of mastication, bolus texture was the same for cheeses with the same lipid content. Low-fat cheeses gave harder bolus than high fat ones, despite being chewed longer, with higher work per cycle and more moisture. Salivary flow rate did not vary among cheese samples but, at the end of mastication, the amount of saliva in boluses d…

Exploring the deviations from scale-invariance of spatial distributions of buildings using a Geographically Weighted Fractal Analysis. An application…

In the early twentieth century a handful of French geographers and historians famously suggested that mainland France comprised two agrarian systems: enclosed field systems with scattered settlements in the central and western France, and openfield systems with grouped settlements in eastern France. This division between grouped and scattered settlements can still be found on the outskirts of urban areas. The objective of this paper is to determine whether the shape of urban areas varies with the type of built patterns in their periphery. To this end, we identify and characterise the local and global deviations from scale-invariance of built patterns in metropolitan France. We propose a new…

Abnormal textures identification based on digital Hilbert optics methods: fundamental transforms and models

2018

The article presents the abnormal textures identification technology based on structural and statistical models of amplitude-phase images (APIm)– multidimensional data arrays (semantic models) and statistical correlation analysis methods using the generalized discrete Hilbert transforms (DHT)– 2D Hilbert (Foucault) isotropic (HTI), anisotropic (HTA) and total transforms – AP-analysis (APA) to calculate the APIm. The identified fragments of textures are obtained as examples of experimental observation of real mammograms contains areas of pathological tissues. The DHT based information technology as conceptual chart description is discussed and illustrated with DHO domain images. As additiona…

Identification des espèces d'arbres à partir de données T-LiDAR Tree species identification using T-LiDAR data

2013

National audience; En raison de l'utilisation croissante des scanners LiDAR terrestre (T-LiDAR) dans le domaine forestier, le développement d'outils logiciels pour la mesure automatique d'attributs d'inventaire forestier est devenu un domaine de recherche important. De nombreux travaux portant sur la localisation des arbres dans un nuage de points, la mesure du diamètre à hauteur de poitrine (DHP) ou la mesure de la hauteur des arbres ont été décrits dans la littérature. Cependant, le problème de l'identification des espèces d'arbres à partir de données T-LiDAR a été peu abordé. La plupart des travaux utilisent des données LiDAR aéroportées et les espèces des arbres sont déterminées à l'éch…

Aiap Design Per 2011. Settimana internazionale della grafica. Trame e tessuti

2011

Aiap Design Per giunge alla sua terza edizione e in questa occasione, visti gli interessanti temi che si susseguono in tutte le edizioni, intendiamo inaugurare una collana che possa raccogliere una serie di spunti di riflessione tali da accompagnare la chermesse. Un documento quindi lontano dal didascalico racconto, che lasciamo invece alle pagine web dedicate, e che vuole invece provare a lanciare delle sporie, dei primi link, da approfondire poi in tutti gli incontri programmati durante la Design Week. Una sorta di pamphlet pindarico e multidisciplinare in grado di raccogliere riflessioni anche lontane o discordanti ma che nel tema proposto trovano raccordo nel tentativo di allargare i co…
