On the classification of visual patterns: systems analysis using detection experiments.

1977

Behavioral experiments are indispensable for the analysis of biological systems for cognition and recognition. When these are carried out as detection experiments three types of description can be used for the problem of visual pattern recognition which allow conclusions to be drawn on the operating function of the system. Provided that the signals to be recognized have additive noise superimposed on them, system description is possible: 1. on the basis on the probabilities of recognition and of mix-up,--2. through the analysis of the transformation of distribution densities of the noise,--3. by means of the measurable distances of the patterns from each other in feature space.-The analysis…

Humectabilidad In-Vivo E In-Vitro En Diferentes Materiales De Lentes De Contacto Y Calidad De La Película Lagrimal

2023

Las lentes de contacto han aumentado en popularidad en las últimas cinco décadas como una opción para la corrección de los errores refractivos del ojo, con un estimado de 140 millones de usuarios en todo el mundo. A pesar de la introducción de nuevas tecnologías y materiales de las lentes de contacto, la interrupción y/o “deserción” en el porte continúa causando problemas a la industria de la contactología. La sequedad y el malestar relacionados con las lentes de contacto continúan siendo reportados por aproximadamente el 30% y 50% de los portadores de lentes, principalmente las molestias al final del día. Una encuesta reciente indico que el 25% de los encuestados habían descontinuado el po…

Understand the visual culture in the classrooms through the postmodern curriculum. ICT as mediators in the production process

2020

espanolEl siguiente articulo forma parte de un trabajo de investigacion vinculado a un estudio de tesis doctoral en el que desgranamos cuestiones de caracter teorico que relacionan la Cultura Visual y las TIC con la educacion en artes en la Facultad de Magisterio de la Universitat de Valencia. Pretendemos promocionar la relevancia de este concepto, no demasiado extendido en las aulas y en la sociedad, con la finalidad de dejar mella en los futuros docentes, discentes y ciudadanos criticos. Una sociedad invadida de imagenes requiere de agentes con capacidad para descifrar los mensajes que en ellas subyacen. Pero no solo la faceta de consumidores (criticos) de imagenes es la que promueve la C…

The Illegible Doctor’s Writing as a Visual Artifact and Creative Stimulation for Art Education

2014

El presente artículo analiza las posibilidades educativas de la particular escritura de los médicos, estudiando la componente gráfica de sus documentos, tanto históricos como recientes. Defendemos la escritura manual como un elemento gráfico importante para la educación artística, a partir de las premisas de la cultura visual. Nos basamos en los resultados positivos de la exposición “Caligrafías de la enfermedad. Letra de médico”, una muestra en la que los visitantes son protagonistas, intérpretes y constructores de significados. Utilizamos la metodología de los estudios de caso, incorporando la observación directa de varios grupos de visitantes. También aportamos otros datos de la experien…

Aplicación, generalización y evaluación del programa PECS en un caso de Trastorno del Espectro Autista

2019

El presente artículo muestra un estudio de caso sobre intervención en la generalización de la comunicación que emplea un niño diagnosticado de TEA. El objetivo fue la creación, aplicación y evaluación de pautas que deben seguir los profesionales del Centro de Educación Especial en el que está matriculado, para que pueda generalizar las habilidades adquiridas del sistema PECS en el aula de audición y lenguaje, al aula de referencia. Para ello se ha seguido un método mixto, empleando el análisis documental, entrevistas y registros de observación cuantificables. A lo largo del proceso se diseñan y construyen las pautas, se realizan reuniones de coordinación, se implementan las instrucciones en…

Pictorial Turn. Saggi di cultura visuale

2017

Il libro, in una nuova edizione completamente rivista e aggiornata, presenta al pubblico italiano i testi più rappresentativi di uno dei protagonisti della visual culture contemporanea. Il pictorial tum è la "svolta"' epistemologica che pone lo studio delle immagini sullo stesso piano di quello del linguaggio. Il libro, in una nuova edizione completamente rivista e aggiornata, presenta al pubblico italiano i testi più rappresentativi di uno dei protagonisti dela visual culture contemporanea. Si tratta di saggi in cui Mitchell introduce nozioni e termini ormai entrati a pieno titolo nel vocabolario critico, come l'alternativa image/picture, le nozioni di metapicture e biopicture, e lo studio…

LeSSS: Learned Shared Semantic Spaces for Relating Multi-Modal Representations of 3D Shapes

2015

In this paper, we propose a new method for structuring multi-modal representations of shapes according to semantic relations. We learn a metric that links semantically similar objects represented in different modalities. First, 3D-shapes are associated with textual labels by learning how textual attributes are related to the observed geometry. Correlations between similar labels are captured by simultaneously embedding labels and shape descriptors into a common latent space in which an inner product corresponds to similarity. The mapping is learned robustly by optimizing a rank-based loss function under a sparseness prior for the spectrum of the matrix of all classifiers. Second, we extend …

Epistemic and didactic values of the demonstrative process in different cultures: a case study in Geometry with Chinese and Italian students

2011

This paper presents same key findings of the research project conducted by G.R.I.M. of Palermo on the approaches to justification and proof in Geometry by investigating how Chinese and Italian teachers and students taught particular geometrical topics refereed to different epistemic and didactic values related to own culture. It was found that Chinese teachers and students emphasized justification of the proof by a stressed visual verification based on some metarules linked with the structure of their own written language and defined as historical Chinese modus operandi in the Jiuzhang Suanshu. The Italians paid close attention to mathematical proof by a hypoxemic deductive system defined on the Euclide’ Elements. The geometrical problem discussed on the paper was defined and presented as “one problem multiple solution problems” and “one problem multiple changes”. Important aspect of the case study discussed in the paper focus on the mediation of knowledge between Chinese and Italian students involved in multicultural class. According to us these kind of activities can establish possibilities for the students to confront their self with different cultural social and educational prospective of knowledge discovering the power of mathematics as tool of negotiation in multicultural class?Settore MAT/04 - Matematiche Complementari

“I am cobalt” Thérèse Moll

2020

Thérèse Moll (1934 - 1961), a little known but by no means secondary figure, is part of the history of visual communication design in which she left a brief but lasting trace. Moll is enrolled at the School of Arts and Crafts in Basel where she meets important designers and teachers including Armin Hoffman, Emil Ruder, Karl Gerstner and Antonio Boggeri. Still very young, she receives an invitation to be a visiting designer at MIT in Boston. At the beginning of 1959, Thérèse Moll arrives in the U.S.A. and during her four-month stay she works with Jacqueline S. Casey and Ralph Coburn at MIT’s Office of Publications, radically modifying the MIT communication, while at the same time introducing…

The what, when, where, and how of visual word recognition

2014

A long-standing debate in reading research is whether printed words are perceived in a feedforward manner on the basis of orthographic information, with other representations such as semantics and phonology activated subsequently, or whether the system is fully interactive and feedback from these representations shapes early visual word recognition. We review recent evidence from behavioral, functional magnetic resonance imaging, electroencephalography, magnetoencephalography, and biologically plausible connectionist modeling approaches, focusing on how each approach provides insight into the temporal flow of information in the lexical system. We conclude that, consistent with interactive a…
