The circle in the relationship between space and body. Photo-essay based on Isidro Blasco and the BAPNE method
2015
En el presente artículo se muestra un estudio visual sobre el espacio educativo universitario en el que se desarrollan enseñanzas sobre percusión corporal. Como marco metodológico se escoge la Investigación Educativa Basada en las Artes Visuales empleándose la obra de un artista como referente conceptual y metodológico. La investigación queda marcada tanto por la referencia visual a la obra de Isidro Blasco – especialmente con la obra “Shanghai planet 2009”-; como por los paralelismos establecidos entre el objeto de estudio de esta investigación -el análisis espacial- y los focos de interés desvelados por los críticos de arte respecto a la obra de este artista. Mediante un discurso visual f…
Human Surfaces
2020
Human Surfaces è un diario visivo interpretativo che mette in luce, in modo originale, un’iconografia di varie e potenziali diversità individuali (l’alter ego, l’attore, il visionario) protagoniste di scene immaginarie ma non per questo meno obiettive. Di Donato si muove in un territorio non solo di osservazione ma di costruzione dell’immagine, a sancire che la fotografia, come tutte le forme visuali autoriali, è un’emanazione che contiene il suo arte fice. Tessendo le fila delle sue visioni l’autore crea intersezioni, riconoscimenti, trasforma zioni, vere e proprie descrizioni dense di ciò che immagina e ritrae, svelando le relazioni di senso affidate alle immagini e all’immaginario. Le su…

Forme e retoriche del fototesto letterario
2016
In ciò che tradizionalmente chiamiamo letteratura esistono forme che definiamo fototesti. Nella loro ormai secolare storia – che di fatto inizia a pochi decenni dall’invenzione della fotografia con il testo di Georges Rodenbach, Bruges la morta (Bruges-la-Morte, 1892) – la teoria letteraria ha avuto costante difficoltà anche semplicemente ad accettarne l’esistenza tra le forme alte di letteratura (per non dire nel canone), preferendo per lo più relegare questi ibridi tra le forme giornalistiche, quando addirittura non ne ha negato l’esistenza amputando l’immagine dal testo e viceversa.
Subjective image fidelity metric based on bit allocation of the human visual system in the DCT domain
1997
Until now, subjective image distortion measures have partially used diverse empirical facts concerning human perception: non-linear perception of luminance, masking of the impairments by a highly textured surround, linear filtering by the threshold contrast frequency response of the visual system, and non-linear post-filtering amplitude corrections in the frequency domain. In this work, we develop a frequency and contrast dependent metric in the DCT domain using a fully non-linear and suprathreshold contrast perception model: the Information Allocation Function (IAF) of the visual system. It is derived from experimental data about frequency and contrast incremental thresholds and it is cons…
The iconic interface for the PIctorial C language
2003
Iconic environments intend to provide expressive tools to implement, to debug and to execute programs. Moreover its pictorial constructs guide the user to design algorithms in an interactive fashion. Visual interfaces are especially required whenever programs run on an heterogeneous and reconfigurable multiprocessor system oriented to image analysis. Pictorial tools help the user to control the scope of variables, and the distribution of the tasks into the processors. In this paper, the general design, the visual-syntax, and the implementation of the first prototype of an iconic user interface for the PIctorial C Language (PICL) are described. >

Reduced reference 3D mesh quality assessment based on statistical models
2015
International audience; During their geometry processing and transmission 3D meshes are subject to various visual processing operations like compression, watermarking, remeshing, noise addition and so forth. In this context it is indispensable to evaluate the quality of the distorted mesh, we talk here about the mesh visual quality (MVQ) assessment. Several works have tried to evaluate the MVQ using simple geometric measures, However this metrics do not correlate well with the subjective score since they fail to reflect the perceived quality. In this paper we propose a new objective metric to evaluate the visual quality between a mesh with a perfect quality called reference mesh and its dis…
No-Reference 3D Mesh Quality Assessment Based on Dihedral Angles Model and Support Vector Regression
2016
International audience; 3D meshes are subject to various visual distortions during their transmission and geometrical processing. Several works have tried to evaluate the visual quality using either full reference or reduced reference approaches. However, these approaches require the presence of the reference mesh which is not available in such practical situations. In this paper, the main contribution lies in the design of a computational method to automatically predict the perceived mesh quality without reference and without knowing beforehand the distortion type. Following the no-reference (NR) quality assessment principle, the proposed method focuses only on the distorted mesh. Specific…
On the use of Deep Reinforcement Learning for Visual Tracking: a Survey
2021
This paper aims at highlighting cutting-edge research results in the field of visual tracking by deep reinforcement learning. Deep reinforcement learning (DRL) is an emerging area combining recent progress in deep and reinforcement learning. It is showing interesting results in the computer vision field and, recently, it has been applied to the visual tracking problem yielding to the rapid development of novel tracking strategies. After providing an introduction to reinforcement learning, this paper compares recent visual tracking approaches based on deep reinforcement learning. Analysis of the state-of-the-art suggests that reinforcement learning allows modeling varying parts of the tracki…
