Estimating intrinsic image from successive images by solving underdetermined and overdetermined systems of the dichromatic model

2020

International audience; Estimating an intrinsic image from a sequence of successive images taken from an object at different angles of illumination can be used in various applications such as objects recognition, color classification, and the like; because, in so doing, it can provide more visual information. Meanwhile, according to the well-known dichromatic model, each image can be considered a linear combination of three components, including intrinsic image, shading factor, and specularity. In this study, at first, two simple independent constrained and parallelized quadratic programming steps were used for computing values of the shading factor and the specularity of each successive of…

A view of extraterrestrial soils

2009

International audience; The nature of soils on celestial bodies other than Earth is a growing area of research in planetary geology. However, disagreement over the significance of these deposits arises in part due to the lack of a unified concept and definition of soil in the literature. The pragmatic definition “medium for plant growth” is taken by some to imply the necessity of biota for soil to exist, and has been commonly adopted in the planetary science community. In contrast, a more complex and informative definition bases on scientific theory: soil is the (bio)geochemically/physically altered material at the surface of a planetary body that encompasses surficial extraterrestrial tell…

Usability of Programming Languages

2016

Programming languages form the interface between programmers (the users) and the computation that they desire the computer to execute. Although studies exist for some aspects of programming language design (such as conditionals), other aspects have received little or no human factors evaluations. Designers thus have little they can rely on if they want to make new languages highly usable, and users cannot easily chose a language based on usability criteria. This SIG will bring together researchers and practitioners interested in increasing the depth and breadth of studies on the usability of programming languages, and ultimately in improving the usability of future languages. nonPeerReviewed

γ‐Agregation operators and some aspects of generalized aggregation problem

2010

We explore questions related to the aggregation operators and aggregation of fuzzy sets. No preliminary knowledge of the aggregation operators theory and of the fuzzy sets theory are required, because all necessary information is given in Section 2. Later we introduce a new class of γ‐aggregation operators, which “ignore” arguments less than γ. Due to this property γ‐aggregation operators simplify the aggregation process and extend the area of possible applications. The second part of the paper is devoted to the generalized aggregation problem. We use the definition of generalized aggregation operator, introduced by A. Takaci in [7], and study the pointwise extension of a γ‐agop. First publ…

Pointwise k-Pseudo Metric Space

2021

In this paper, the concept of a k-(quasi) pseudo metric is generalized to the L-fuzzy case, called a pointwise k-(quasi) pseudo metric, which is considered to be a map d:J(LX)×J(LX)⟶[0,∞) satisfying some conditions. What is more, it is proved that the category of pointwise k-pseudo metric spaces is isomorphic to the category of symmetric pointwise k-remote neighborhood ball spaces. Besides, some L-topological structures induced by a pointwise k-quasi-pseudo metric are obtained, including an L-quasi neighborhood system, an L-topology, an L-closure operator, an L-interior operator, and a pointwise quasi-uniformity.

La questione abitativa in Sicilia

2011

Da qualche anno la questione abitativa ha assunto una nuova centralità. Il mercato immobiliare, infatti, risponde con sempre maggiore difficoltà ai fabbisogni delle fasce sociali più deboli. L'articolo vuole restituire, in particolare, quanto sta accedendo oggi in Sicilia in materia di politiche abitative.

Ai margini delle politiche sociali. Il disagio abitativo tra nuovi contesti e nuovi soggetti

2012

Come i programmi complessi hanno contribuito ad innovare le politiche abitative in Italia? A partire da tale interrogativo, il saggio cerca di comprendere quali elementi possono essere utili per la costruzione di una rinnovata poltica abitativa nel mutato contesto socio-economico. In particolare l'articolo si sofferma sul contributo che i programmi complessi hanno dato al ripensamento delle tradizionali politiche per la casa.

The Five-Pillar Model of Parties’ Migration into the Digital

2021

Scholars have examined how political parties cope with web-based technologies for about 20 years. This body of literature on party digitalisation covers many different aspects of parties’ migration into the digital, yet usually, the term digitalisation is used equally for all kinds of web-related changes in party behaviour and routines. This contribution distinguishes five key dimensions (pillars) of parties’ migration into the digital, which resonate with classic approaches of party research. These pillars cover (A) membership, (B) leaders and candidates, (C) policy program, (D) public image, and (E) resources. Each pillar consists of three bricks addressing sub-dimensions. This enables a …
