Shape Reconstruction of Metallic Objects by Artificial Vision
1997
Quality control in industrial applications has greatly benefited from the development of tools like artificial vision. The artificial vision approach of quality control has the advantage of being able to perform both non-destructive and contactless controls as well as to work mostly in real time. However, in the case of non planar objects to be controlled, dimensional control may become hard to realize. Indeed, due to the bidimensional aspect of the images, a loss of information is unavoidable. Consequently, obtaining depth information from a planar image is not obvious. Most of the existing methods use several cameras1 or several light sources2, this leads to an increase in the processing …
On the Use of Preferential Weights in Interactive Reference Point Based Methods
2009
We introduce a new way of utilizing preference information specified by the decision maker in interactive reference point based methods. A reference point consists of aspiration levels for each objective function. We take the desires of the decision maker into account more closely when projecting the reference point to become nondominated. In this way we can support the decision maker in finding the most satisfactory solutions faster. In practice, we adjust the weights in the achievement scalarizing function that projects the reference point. We demonstrate our idea with an example and we summarize results of computational tests that support the efficiency of the idea proposed.
The iterative object symmetry transform
2005
This paper introduces a new operator named the Iterated Object Transform that is computed by combining the Object Symmetry Transform with the morphological operator erosion. This new operator has been applied on both binary and gray levels images showing the ability to grasp the internal structure of a digital object. We present some experiments on real images in face analysis.
“Nos inventamos un mundo que no existía”. Una profesión de riesgo.
2019
Since the end of Franco's dictatorship, editorial censorship has been an object of interdisciplinary study that has been incorporating, to the initial analysis of the constitution and nature of censorship, the study of a variety of case studies that are resizing the phenomenon. On the one hand, in the context of memory studies, it is necessary to analyze what effects censorship had on the configuration of cultural memory. On the other hand, censorship has a considerable effect on publishing strategies, both in itself and because it fosters self-censorship and countercensorship. In particular, this article explores the work of women publishers who, in the Barcelona of the 1960s and 1970s, op…
Integration of multiple range and intensity image pairs using a volumetric method to create textured three-dimensional models
2001
We present a volumetric approach to three-dimensional (3D) object modeling that differs from previous techniques in that both object texture and geometry are considered in the reconstruc- tion process. The motivation for the research is the simulation of a thermal tire inspection station. Integrating 3D geometry information with two-dimensional thermal images permits the thermal informa- tion to be displayed as a texture map on the tire structure, enhanc- ing analysis capabilities. Additionally, constructing the tire geometry during the inspection process allows the tire to be examined for structural defects that might be missed if the thermal data were textured onto a predefined model. Exp…
Hidden Markov Random Field model and BFGS algorithm for Brain Image Segmentation
2016
Brain MR images segmentation has attracted a particular focus in medical imaging. The automatic image analysis and interpretation became a necessity. Segmentation is one of the key operations to provide a crucial decision support to physicians. Its goal is to simplify the representation of an image into items meaningful and easier to analyze. Hidden Markov Random Fields (HMRF) provide an elegant way to model the segmentation problem. This model leads to the minimization problem of a function. BFGS (Broyden-Fletcher-Goldfarb-Shanno algorithm) is one of the most powerful methods to solve unconstrained optimization problem. This paper presents how we combine HMRF and BFGS to achieve a good seg…
Symbols and Meanings in Breast Cancer Awareness Campaigns
2013
This article examines symbols and meanings in breast cancer awareness campaigns, and the ways in which multifarious actors draw attention to the disease. We discuss what the various campaigns and initiatives can indicate, above and beyond creating breast cancer awareness. Our data stem from sources such as printed material, the Internet, and events. From these sources we have singled out and explored objects, text, and visual expressions, looking in particular for metaphors and symbolic aspects. In this article we present six “images” indicating the underlying patterns that we found. We have called the images Re-enchantment of femininity, Infantilization, Corporate profit-making, Objectific…
Product Placement in Video Games as a Marketing Strategy: An Attempt to Analysis in Disney Company
2011
What is the best marketing strategy in video games? The literature is not unanimous in upholding the best strategy. Researchers investigating advertising effectiveness disagree on the value of product placement in video games and the methods firms should use with product placement strategies. The state of the question now must figure out the dichotomy between two perspectives: to identify the differences in the effectiveness of product placement in video games when using “traditional placement approaches” compared to the “branded entertainment approach”. The “traditional approach” to product placement in video games involves the product appearing as a visual object that is passive, used by …
Monográfico. Cine: Arte e industria. [DOI:10.37785/nw.v4n2.a6]
2020
En 1895, en plena segunda revolución industrial, el cine emprendió su andadura con la patente del “cine- matógrafo” de los hermanos Lumière, un ingenio que, gracias a un procedimiento mecánico, permitía no solo la captación de imágenes “reales” –como lo hiciera en su momento la fotografía, pero esta vez añadiéndoles movimiento– sino también la proyección de esa continuidad de imágenes impresionadas. No cabe la menor duda de que con el objeto nació una industria, item est, una actividad lucrativa que explotaba la novedosa invención técnica con el fin de producir bienes comerciables que ofertar a la ociosa sociedad burguesa de finales del s. XIX y principios del s. XX. Rápid…
A Proposal to Enrich Teachers' Perception of the State of the World: First results
2003
The 'state of the world' has become an object of growing concern during recent decades. For this reason educators have been asked to contribute to public awareness and understanding of the problems and challenges related to our planet's future, in order to make possible citizens' participation in well-grounded decision-making. In spite of these appeals, attention paid by science teachers and science education researchers to the present state and future of the world is still very slight and constitutes a serious missing dimension in science teachers' education. In this article we describe a workshop conceived to favour a better teacher perception of global problems and possible remedies, as …
