Multi-channel chromatic transformations for nonlinear color pattern recognition

2002

We present a new approach for color pattern recognition based on multi-channel nonlinear correlations. High discrimination capability is obtained in comparison with common linear multi-channel detection methods. We apply the nonlinear morphological correlation to different color channel decompositions as RGB and ATD channels. Moreover, in order to improve the discrimination we have introduced a new color transformation. When a high selectivity is required, the combination of the nonlinear correlation and the new color decomposition yields to detect the object using just a single channel. Simulation results are provided.

Application of the S-CIELAB color model to processed and calibrated images with a colorimetric dithering method.

2009

This work uses the S-CIELAB color model to compare images that have been calibrated and processed using a colorimetric dithering method which simulates increments in viewing distance. Firstly, we obtain XYZ calibrated images by applying the appropriate color transformations to the original images. These transformations depend on whether the image is viewed on a display device or encoded by a capture device, for example. Secondly, we use a colorimetric dithering method consisting of a partitive additive mixing of XYZ tristimulus values. The number of dithered pixels depends on simulated viewing distance. The dithered tristimulus values are transformed to digital data to observe the dithering…

Shape indices to identify regional differences in otolith morphology of comber, Serranus cabrilla (L., 1758)

2003

Summary Sagittal otoliths from the Atlantic and Mediterranean regions of Serranus cabrilla L. were compared using shape indices (form-factor, roundness, circularity, rectangularity, ellipticity and eccentricity). Regional differences were best described by form-factor, circularity and eccentricity variables. The canonical discriminant functions were built with form-factor or rectangularity indices. The results indicated slight regional variations. The G-test was the criterion more useful to identify the otolith origin in the discriminant analysis.

Unraveling the extracellular matrix-tumor cell interactions to aid better targeted therapies for neuroblastoma

2021

Treatment in children with high-risk neuroblastoma remains largely unsuccessful due to the development of metastases and drug resistance. The biological complexity of these tumors and their microenvironment represent one of the many challenges to face. Matrix glycoproteins such as vitronectin act as bridge elements between extracellular matrix and tumor cells and can promote tumor cell spreading. In this study, we established through a clinical cohort and preclinical models that the interaction of vitronectin and its ligands, such as αv integrins, are related to the stiffness of the extracellular matrix in high-risk neuroblastoma. These marked alterations found in the matrix led us to speci…

Communication Design for the Dissemination of Scientific Knowledge. Languages, Tools, Technologies, Collaborative Processes for Museum Education

2019

Il testo propone l’analisi di un articolato processo di ricerca-azione, avviato in occasione di alcune sperimentazioni didattico-scientifiche nate dalla collaborazione tra le discipline del design, della rappresentazione multimediale, delle scienze botaniche nell’Università di Palermo. L’esperienza proposta è stata centrata sulla comunicazione scientifica e sull’elaborazione di prodotti comunicativi per la didattica museale e istituzionale dell’Orto Botanico di Palermo. In quest’occasione sono stati sperimentati strumenti progettuali, tecnologie e modalità di espressione successivamente rielaborati anche in un progetto di sviluppo territoriale, che ha portato alla realizzazione del “Micromu…

Mobile Communication: Media Effects

2017

This entry introduces the reader to various media effects of mobile communication devices. The special focus is on mobile phones. The entry begins with a presentation of media effects on communication practices, on users, as well as on interlocutors and bystanders. It continues by analyzing the reverse effects of users on the redesign of mobile media. Lastly, the issues of how mobile communication is connected to social and geographical surroundings and how the use of mobile communication devices is related to the social structures of society are addressed. The entry concludes with a discussion of the media effects of mobile communication in the future. Keywords: digital media; mobile commu…

Reader Comments Agentive Power in COVID-19 Digital News Articles: Challenging Parascientific Information?

2022

The recent COVID-19 pandemic has triggered an enormous stream of information. Parascientific digital communication has pursued different avenues, from mainstream media news to social networking, at times combined. Likewise, citizens have developed new discourse practices, with readers as active participants who claim authority. Based on a corpus of 500 reader comments from The Guardian, we analyse how readers build their authorial voice on COVID-19 news as well as their agentive power and its implications. Methodologically, we draw upon stance markers, depersonalisation strategies, and heteroglossic markers, from the perspective of discursive interpersonality. Our findings unearth that stan…

The soundslide report : innovative journalism or misplaced works of art?

2014

Published version of an article in the journal: Nordicom Review. Also available from the publisher at: http://dx.doi.org/10.2478/nor-2014-0007 Open Access The audio slideshow-or soundslide report-represents a new format for journalistic reporting on online news sites. It is not very widely used, but it has certain discursive and aesthetic potentials indicating that it could contribute substantially to the ecology of journalistic genres. The article offers an illustration and discussion of these potentials, asking how the format communicates and how it affects journalism in general. Starting out with a close reading of a sample text and a discussion of the format's position in a network of g…

Short article: Does the brain regularize digits and letters to the same extent?

2009

The cognitive system does not just act as a mirror from the sensory input; instead, it tends to normalize this information. Given that letter processing seems to be much more specialized than digit processing in the cortex, we examined whether the regularization process occurs differently from digits to letters than from letters to digits: We employed a masked priming same/different experiment (e.g., probe, VESZED; prime, V35Z3D; and target, VESZED). When embedded in letter strings, digits that resemble letters (e.g., 3 and 5 in V35Z3D-VESZED) tend to be encoded in a letter-like manner, whereas when embedded in digit strings, letters that resemble digits (e.g., E and S in 9ES7E2–935732) te…
