Rotation-Invariant Texture Retrieval via Signature Alignment Based on Steerable Sub-Gaussian Modeling
2008
This paper addresses the construction of a novel efficient rotation-invariant texture retrieval method that is based on the alignment in angle of signatures obtained via a steerable sub-Gaussian model. In our proposed scheme, we first construct a steerable multivariate sub-Gaussian model, where the fractional lower-order moments of a given image are associated with those of its rotated versions. The feature extraction step consists of estimating the so-called covariations between the orientation subbands of the corresponding steerable pyramid at the same or at adjacent decomposition levels and building an appropriate signature that can be rotated directly without the need of rotating the im…
Spherical nonlinear correlations for global invariant three-dimensional object recognition
2007
We define a nonlinear filtering based on correlations on unit spheres to obtain both rotation- and scale-invariant three-dimensional (3D) object detection. Tridimensionality is expressed in terms of range images. The phase Fourier transform (PhFT) of a range image provides information about the orientations of the 3D object surfaces. When the object is sequentially rotated, the amplitudes of the different PhFTs form a unit radius sphere. On the other hand, a scale change is equivalent to a multiplication of the amplitude of the PhFT by a constant factor. The effect of both rotation and scale changes for 3D objects means a change in the intensity of the unit radius sphere. We define a 3D fil…
Invariant Feature Matching for Image Registration Application Based on New Dissimilarity of Spatial Features
2016
An invariant feature matching method is proposed as a spatially invariant feature matching approach. Deformation effects, such as affine and homography, change the local information within the image and can result in ambiguous local information pertaining to image points. New method based on dissimilarity values, which measures the dissimilarity of the features through the path based on Eigenvector properties, is proposed. Evidence shows that existing matching techniques using similarity metrics--such as normalized cross-correlation, squared sum of intensity differences and correlation coefficient--are insufficient for achieving adequate results under different image deformations. Thus, new…
La tutela penale del segreto commerciale in Italia. Fra esigenze di adeguamento e possibilità di razionalizzazione
2019
Il contributo si concentra sulla disciplina penale italiana in materia di segreto commerciale, e ha l’intento di verificare se la recente riforma legislativa (D. Lgs. n. 63/2018) sia riuscita a conformare l’ordinamento domestico alle moderne istanze della data-driven economy. La novella ha modificato la struttura e l’oggetto di tutela dell’art. 623 c.p., e ha comportato inoltre un avvicinamento della disciplina penale al sistema di tutela civilistico predisposto dal codice della proprietà industriale (art. 98 c.p.i.). Tale avvicinamento pone all’interprete non pochi dubbi in merito alla compatibilità tra le due forme di protezione, dubbi enfatizzati dalla recente giurisprudenza convenzional…
Deep structural setting of the Rocca Busambra Ridge (central-western Sicily): a seismostratigraphic reconstruction

3D structural modeling and restoration of the Apennine-Maghrebian chain in Sicily: Application for non-cylindrical fold-and-thrust belts
2019
International audience; Thirteen seismic reflection profiles and field observations have been used to build a three-dimensional watertight geological model of the sub-surface architecture of the Trapanese carbonate platform unit of the Apennine-Maghrebian chain in the Mt. Kumeta and Mt. Rocca Busambra (NW Sicily, Italy). Either a single step or a two-step thrust-fault deformation model is acceptable on the basis of seismic interpretation but the integration of 3D model reconstruction and 3D geomechanical restoration, validates only the scenario with a single stage of deformation.The 3D model highlights along strike variations of the structural style for the Trapanese unit where pre-existing…
A neural network approach to movement pattern analysis.
2004
Movements are time-dependent processes and so can be modelled by time-series of coordinates: E.g., each articulation has geometric coordinates; the set of the coordinates of the relevant articulations build a high-dimensional configuration. These configurations--or "patterns"--give reason for analysing movements by means of neural networks: The Kohonen Feature Map (KFM) is a special type of neural network, which (after having been coined by training with appropriate pattern samples) is able to recognize single patterns as members of pattern clusters. This way, for example, the particular configurations of a given movement can be identified as belonging to respective configuration clusters, …

The interpretation of prehistoric visual expression in indoor museums
2011
Representing Prehistory in museums, with all the contradictions that the term “representation” may imply, is always very controversial from the interpretative point of view, implicating a series of different philosophical and scientific positions, both on Prehistory itself, and on the way of introducing it to the public, particularly today with the resurfacing of the need to dedicate some attention also to the social and the so-called “immaterial” contexts, to the myths, the rites, the cults, to the interpretation of life and nature, overcoming the obsolete concept of the museums exposing manufactured articles. In the long decontestualization process of the objects involving, unfortunately,…
Implementare il patrimonio archivistico: ricostruzione virtuale di una villa non realizzata di Giuseppe Samonà in Sicilia
2023
Questo saggio vuole essere una testimonianza dell’importanza culturale e cognitiva degli archivi (del progetto) intesi come patrimonio pubblico. L’azione di re-immaginarli può costituire un veicolo per la loro conoscenza? Con l’analisi di un caso-studio di un’abitazione non realizzata di un architetto del Novecento come Giuseppe Samonà si prova a verificare l’efficacia degli strumenti digitali per l’interpretazione dell’architettura come mezzi per l’implementazione comunicativa di un archivio.
