Influence of composition and texture on in-mouth sodium release and saltiness perception during consumption of semi-hard cheeses
2011
Sodium content in human diet being excessive in many industrialized country, health authorities recommended its progressive reduction in food products in order both to improve public health and to decrease health cost (1). Cheese is one of the most important sodium vectors. However, salt (NaCl) is not only responsible for saltiness but is also implied in other functionalities such as flavour enhancement, texture, preservation (2). Keeping a good acceptability of food by the consumer at lower sodium chloride concentration is a real challenge for cheese industry to avoid negative consequences. To reach this goal, it is necessary to understand the role of cheese structure and composition on th…
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…
2018
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…
Définir, dénommer et traduire l'onctuosité : regards croisés sur une propriété gustative et ses dénominations en français, anglais et allemand
2006
International audience; Un simple coup d'œil sur les rayons crèmerie d'un supermarché ou sur les prospectus publicitaires suffit à s'en convaincre : onctueux est un attribut fort prisé en marketing alimentaire. Un test rapide sur google le confirme par ailleurs : pour les seules structures N + A, le moteur de recherche fournit une multitude d'occurrences pour ce domaine avec des syntagmes comme fromage blanc onctueux, potage onctueux mais aussi bûche de Noël au cœur onctueux, riz onctueux ou encore beurre de pomme onctueux. L'objectif de cette contribution est ainsi d'interroger les multiples emplois de l'adjectif onctueux en français et d'en envisager les équivalents possibles en anglais e…
Features extraction on complex images
2005
The accessibility of inexpensive and powerful computers has allowed true digital holography to be used for industrial inspection using microscopy. This technique allows the capture of a complex image (i.e., one containing magnitude and phase), and the reconstruction of the phase and magnitude information. Digital holograms give a new dimension to texture analysis, since the topology information can be used as an additional way to extract features. This new technique can be used to extend previous work on the image segmentation of patterned wafers for defect detection. The paper presents a comparison between the features obtained using Gabor filtering on complex images under illumination and…
Statistical methods for texture analysis applied to agronomical images
2008
For activities of agronomical research institute, the land experimentations are essential and provide relevant information on crops such as disease rate, yield components, weed rate... Generally accurate, they are manually done and present numerous drawbacks, such as penibility, notably for wheat ear counting. In this case, the use of color and/or texture image processing to estimate the number of ears per square metre can be an improvement. Then, different image segmentation techniques based on feature extraction have been tested using textural information with first and higher order statistical methods. The Run Length method gives the best results closed to manual countings with an averag…
A statistical model for magnitudes and angles of wavelet frame coefficients and its application to texture retrieval
2014
Abstract This paper presents a texture descriptor based on wavelet frame transforms. At each position in the image, and for each resolution level, we consider both vertical and horizontal wavelet detail coefficients as the components of a bivariate random vector. The magnitudes and angles of these vectors are computed. At each level the empirical histogram of magnitudes is modeled by a Generalized Gamma distribution, and the empirical histogram of angles is modeled by a different version of the von Mises distribution that accounts for histograms with 2 modes. Each texture is characterized by few parameters. A new distance is presented (based on the Kullback–Leibler divergence) that allows g…
Analyse spectrale et texturale de données à haute résolution pour la détection automatique des maladies de la vigne
2019
‘Flavescence dorée’ is a contagious and incurable disease present on the vine leaves. In order to contain the infection, the regulations require growers to control each of the vine rows and to remove the suspect vine plants. This monitoring is done on foot during the harvest and mobilizes many people during a strategic period for viticulture. In order to solve this problem, the DAMAV project (Automatic detection of Vine Diseases) aims to develop a solution for automated detection of vine diseases using a micro-drone. The goal is to offer a turnkey solution for wine growers. This tool will allow the search for potential foci, and then more generally any type of vine diseases detectable on th…
Influence of soil properties on the aggregation of some Mediterranean soils and the use of aggregate size and stability as land degradation indicators
2001
Abstract Soil aggregation in relation to other soil properties was studied along a climatological transect in the Southeast of Spain. Three sites were selected along this transect ranging from semiarid to subhumid climatological conditions. The aggregate size distribution, the macro and microaggregate stability of the superficial soil horizon and their relations with other soil properties were analysed. Large aggregates (>10, 10–5, 5–2 mm) were present in highest proportions in the most arid of the studied areas. These large aggregates were associated with high values of water-stable microaggregates; however, they did not improve soil structure and are related to high bulk densities and low…
