123D Catch: efficiency, accuracy, constraints and limitations in architectural heritage field

2013

Today, the accurate and detailed reconstruction of geometric models of real objects has become a common process. The diffusion of Image-based 3D modeling techniques, through image-based free, low cost and open source software, have increased drastically in the past few years, especially in the sector of Cultural Heritage (Architecture, Archeology, Urban planning). Nevertheless, web based software (ARC3D, 123D Catch, Hyp3D, my3Dscanner) offer another opportunity respect the desktop systems: they use the power of cloud computing to carry out a semi-automatic data processing. In this way is overcome the considerably slowing-down of the computer of hardware-heavy approaches. Our research inves…

Reconstruction Improvement in Integral Fourier Holography by Micro-Scanning Method

2015

Although integral holography has many promising advantages in the field of 3D imaging, the resolution of reconstructed holographic image is still limited by the insufficient information captured. To improve the reconstruction quality, an integral Fourier holographic imaging method based on micro-scanning of the micro-lens array is proposed in this paper. The micro-scanning of the micro-lens array can increase the sampling rate in spatial frequency domain and the information of the generated Fourier hologram, which will eventually eliminate the overlapping effect in the reconstructed 3D image. Experiments for different micro-scanning modes are carried out to verify the feasibility of the pro…

Smart Technologies for Improved Software Maintenance

2015

Steadily increasing complexity of software systems makes them difficult to configure and use without special IT knowledge. One of the solutions is to improve software systems making them “smarter”, i.e. to supplement software systems with features of self-management, at least partially. This paper describes several software components known as smart technologies, which facilitate software use and maintenance. As to date smart technologies incorporate version updating, execution environment testing, self-testing, runtime verification and business process execution. The proposed approach has been successfully applied in several software projects.

A Case Study of Open Source Software Development in Proteomic Area: The LIMS ePims

2008

The objective of this paper is to provide an illustrative feedback on development of Open Source software among several partners. We describe the first stage of the design of a specific software package, namely a customized Laboratory Information Management System (LIMS) for biology applications. This software package is structured in several modules which are reusable and can be customized for other applications. In this paper, we address the problem of multi-licensing for the same software tools due to the participation of several partners, the reuse of code source, and the subsequent distribution of this produced software.

A wireless battery charger architecture for consumer electronics

2012

In this paper, an innovative design of a wireless battery charger for portable electronic devices is proposed. The wireless power transfer is implemented through the magnetic coupling between a power transmitter, which is connected to the grid, and a power receiver, which is integrated inside the load device. An innovative receiver architecture which heavily improves the power conversion efficiency is presented. The proposed solution is standard compliant and suitable for IC implementation. A comparison between a conventional and the proposed receiver architectures is carried out by SPICE simulations. As shown by simulation results, a power efficiency increase by 40% is provided by the prop…

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 …

Motion estimation and reconstruction of piecewise planar scenes from two views

2010

The task of recovering the camera motion relative to the environment (motion estimation) is fundamental to many computer vision applications. We present an algorithm for reconstruction of piece-wise planar scenes from only two views and based on minimum line correspondences. We first recover camera rotation by matching vanishing points based on the methods already exist in the literature and then recover the camera translation by searching among a family of hypothesized planes passing through one line. Unlike algorithms based on line segments, the presented algorithm does not require an overlap between two line segments or more than one line correspondence across more than two views to reco…

“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…

La investigación en Ciencias Laborales como una nueva dimensión del alumnado universitario. Una experiencia innovadora

2016

Profesorado del Grado de Relaciones Laborales y Recursos Humanos de la Universitat de València, se planteó en el curso 2013-2014, y dado que la titulación había pasado de Diplomatura a Grado, la necesidad de fomentar entre el alumnado la orientación investigadora, opción hasta dicho momento difícil de desarrollar. Por eso, a través del desarrollo del proyecto de innovación en dicho curso «Medios para la difusión de resultados de investigaciones en Ciencias Laborales», se creó una web (http://inveslab.blogs.uv.es/) en la que se recogieron los resultados obtenidos del mismo, un repositorio con los medios existentes para la difusión de los resultados de investigaciones en Ciencias Laborales. T…
