Corrigendum to “Electrophysiological signatures of masked transposition priming in a same-different task: Evidence with strings of letters vs. pseudo…
2012
wo images were inadvertently left out of the 2nd paragraph of the reviously published article. Please see corrected paragraph and mages below. In a series of behavioural experiments, Garcia-Orza et al. [10] xamined whether masked transposition priming is specific to leter processing. They employed a masked priming same-different atching task in which participants were required to press a utton if cue and target were the same and to press another utton if cue and target were different (see [15,16] for reviews f this task). A briefly presented transposed-letter masked prime as presented immediately before the target stimulus. Garciarza et al. ([10] Experiments 1–4]) found a masked transpositi…
Complex networks : application for texture characterization and classification
2008
This article describes a new method and approch of texture characterization. Using complex network representation of an image, classical and derived (hierarchical) measurements, we presente how to have good performance in texture classification. Image is represented by a complex networks : one pixel as a node. Node degree and clustering coefficient, using with traditionnal and extended hierarchical measurements, are used to characterize ”organisation” of textures.
Ownership protection of plenoptic images by robust and reversible watermarking
2018
Abstract Plenoptic images are highly demanded for 3D representation of broad scenes. Contrary to the images captured by conventional cameras, plenoptic images carry a considerable amount of angular information, which is very appealing for 3D reconstruction and display of the scene. Plenoptic images are gaining increasing importance in areas like medical imaging, manufacturing control, metrology, or even entertainment business. Thus, the adaptation and refinement of watermarking techniques to plenoptic images is a matter of raising interest. In this paper a new method for plenoptic image watermarking is proposed. A secret key is used to specify the location of logo insertion. Employing discr…
Area-Based Depth Estimation for Monochromatic Feature-Sparse Orthographic Capture
2018
With the rapid development of light field technology, depth estimation has been highlighted as one of the critical problems in the field, and a number of approaches have been proposed to extract the depth of the scene. However, depth estimation by stereo matching becomes difficult and unreliable when the captured images lack both color and feature information. In this paper, we propose a scheme that extracts robust depth from monochromatic, feature-sparse scenes recorded in orthographic sub-aperture images. Unlike approaches which rely on the rich color and texture information across the sub-aperture views, our approach is based on depth from focus techniques. First, we superimpose shifted …
GPU-accelerated integral imaging and full-parallax 3D display using stereo-plenoptic camera system
2019
Abstract In this paper, we propose a novel approach to produce integral images ready to be displayed onto an integral-imaging monitor. Our main contribution is the use of commercial plenoptic camera, which is arranged in a stereo configuration. Our proposed set-up is able to record the radiance, spatial and angular, information simultaneously in each different stereo position. We illustrate our contribution by composing the point cloud from a pair of captured plenoptic images, and generate an integral image from the properly registered 3D information. We have exploited the graphics processing unit (GPU) acceleration in order to enhance the integral-image computation speed and efficiency. We…
New Method of Microimages Generation for 3D Display
2018
In this paper, we propose a new method for the generation of microimages, which processes real 3D scenes captured with any method that permits the extraction of its depth information. The depth map of the scene, together with its color information, is used to create a point cloud. A set of elemental images of this point cloud is captured synthetically and from it the microimages are computed. The main feature of this method is that the reference plane of displayed images can be set at will, while the empty pixels are avoided. Another advantage of the method is that the center point of displayed images and also their scale and field of view can be set. To show the final results, a 3D InI dis…
La genitorialita` procreativa nella coppia omoaffettiva (femminile). Riflessioni a margine di Corte cost. n. 221/2019
2020
Il contributo esamina criticamente la sentenza della Corte costituzionale n. 221 del 2019, che ha affermato la legittimità costituzionale delle previsioni della legge 19 febbraio 2004, n. n. 40, che vietano l’accesso alle tecniche di procreazione medicalmente assistita alle coppie dello stesso sesso. Sulla base di una lettura evolutiva delle regole e dei principî costituzionali e convenzionali implicati, il saggio giunge a una diversa soluzione interpretativa, sostenendo la riconoscibilità del diritto alla genitorialità procreativa degli individui ad orientamento omoaffettivo e la sua compatibilità con l’interesse della prole a nascere e a crescere in un nucleo familiare idoneo ad assicurar…
Conductas sexuales online y sus motivaciones: Una aproximación desde la diversidad sexual
2020
El uso de Internet con objetivos sexuales (cibersexo) es una actividad cada vez más generalizada en todos los sectores de la población. Sin embargo, el modo en el que se realiza (frecuencia, tipos de actividad sexual online –ASO–, motivaciones, etc.) puede cambiar en función de características como la orientación sexual. Cuando el hecho de sentir atracción sexual hacia personas del mismo sexo suponía mayor rechazo y estigmatización que en la actualidad, el cibersexo constituía un espacio seguro donde experimentar con la sexualidad; así, era fácil comprender que su consumo entre personas homosexuales y bisexuales fuera superior. Actualmente, su empleo como espacio seguro parece quedar en seg…
Mancato contro-esame dei testimoni a carico e iniquità del processo penale
2022
This is a note to the judgment in the case Faysal Pamuk v. Turkey (application no. 430/13), rendered by the European Court of Human Rights. The contribution explores the violation of Article 6 §§ 1 (right to a fair trial) and 3 (d) (right to obtain attendance and examination of witnesses) of the European Convention on Human Rights. The case concerned Mr Pamuk’s trial on terrorism-related charges, in particular the use of evidence that had been given in other jurisdictions in the absence of Mr Pamuk or his counsel following letters of request. The Court found in particular that letters of request and examining witnesses in other jurisdictions could not be considered an adequate method of ens…
ALTERAZIONI DEL RECETTORE OCULARE E COMPENSI DELLA COLONNA CERVICO-DORSALE: PARAMETRI STABILOMETRICI
2009
Scopo dello studio è stato quello di analizzare la relazione tra atteggiamento scoliotico dorsale e difetti di convergenza oculare. In 40 soggetti giovani adolescenti maschi di età compresa tra 10 e 12 anni è stata eseguita una valutazione delle curve rachidee con scoliosometro ed un esame stabilometrico mediante piattaforma Baropodometrica Elettronica Modulare “Diagnostic Support”, da cui sono stati ricavati la velocità di variazione, la deviazione media coronale (x-medio), la deviazione media sagittale (y-medio) e la superficie e lunghezza dello statokinesigramma. Inoltre, per l’analisi della funzionalità del recettore oculare, sono stati effettuati il test di convergenza oculare e il cov…
