A Parallel Face Detection System Implemented on FPGA
2007
In this paper, we introduce a methodology for designing a system for face detection and its implementation on FPGA. The chosen face detection method is the well-known convolutional face finder (CFF) algorithm, which consists in a pipeline of convolutions and subsampling operations. Our goal is to define a parallel architecture able to process efficiently this algorithm. We present a dataflow based architecture algorithm adequation (AAA) methodology implemented using the SynDEx software, in order to find the best compromise between the processing power and functionality requirement of each processor element (PE), and the efficiency of algorithm parallelization. We describe a first implementa…
ISFET drawbacks minimization using a novel electronic compensation
2004
Ion sensitive field effect transistor (ISFET) and membrane field effect transistor (MEMFET) have some drawbacks related to: long-term drift, hysteresis and thermal drift. These factors limit the accuracy of ISFET/MEMFET based measurements systems, specially for continuous or long period measurements. Due to its accuracy, repeatability and easy-to-use features, electronic instrumentation systems are the best tools to design ISFET/MEMFET based measurement systems. A well-designed hardware and a qualified virtual instrumentation software are the key factors to overcome and compensate hysteresis, thermal and long-term drifts ISFET/MEMFET limitations. The paper is dedicated to show an instrument…
Like a Flame: Remembering Giovanni Tranchina
2012
When, in October 2010, the Law Faculty of Palermo University celebrated 50 years of the teaching of Giovanni Tranchina on the occasion of his farewell public lecture on “The right to the service of hope,” colleagues and students presented him with a plaque: a simple, unadorned silver sheet which bore a message—engraved not only in the metal—conveying the faculty’s “inexpressible gratitude to a Master of law and life.” At the top of the plaque we had also decided to have engraved a phrase of Piero Calamandrei: a reflection on the “square boxes of procedural law,” whose study “is sterile abstraction, unless it is also the study of the living man.” It seemed that this reference to the deeper d…
El legado de Vicente Ripollés Pérez (1867-1943) en el Real Colegio Seminariod e Corpus Christi de Valencia: visión global y transferencia
2019
Vicente Ripollés Pérez (1867-1943) fue unos de los maestros de capilla españoles más interesantes entre los siglos XIX y XX; destacó como compositor, director, musicólogo y por su liderazgo en el movimiento cecilianista. Llegó a ser nombrado canónigo de la Catedral de Valencia y fue maestro de capilla en las catedrales de Tortosa, Sevilla y el Real Colegio de Corpus Christi en Valencia. A esta última institución legó su archivo y biblioteca que han sido catalogados recientemente y que contienen más de ochocientos do-cumentos. Ripollés merecería un estudio monográfico amplio que excede a las limitaciones de este texto. El objetivo de este trabajo es ofrecer una visión global y crítica sobre …
Supporting Impact Analysis by Program Dependence Graph Based Forward Slicing
2007
Since software must evolve to meet the typically changing requirements, source code modifications can not be avoided. Impact analysis is one of the central and relatively demanding tasks of software maintenance. It is constantly needed while aiming at ensuring the correctness of the made modifications. Due to its importance and challenging nature automated support techniques are required. Theoretically, forward slicing is a very suitable technique for that purpose. Therefore, we have implemented a program dependence graph (PDG) based tool, called GRACE, for it. For example, due to the typical rewritings of Visual Basic programs there is a great need to support their impact analysis. However…
A Visual Introduction to Cubic Surfaces Using the Computer Software Spicy
2003
At the end of the 19th century geometers like Clebsch, Klein and Rodenberg constructed plaster models in order to get a visual impression of their surfaces, which are so beautiful from an abstract point of view. But these were static visualizations. Using the computer program Spicy 1, which was written by the second author, one can now draw algebraic curves and surfaces depending on parameters interactively.
Visual dynamic environment for distributed systems
2002
Algorithms, based on information fusion, are often embodied in visual perception systems. Distributed architectures have been recently proposed to perform integrated computation. The complexity of distributed systems regards both their design, and the software environment to develop applications. Visual and iconic programming style intends to provide expressive tools to implement, to debug, and to execute programs in distributed environment. Multi-layers graphs languages seem suitable to handle such complexity. This paper describes the design of a visual dynamic environment (VDE), which is based on a graph-grammar. A new class of dynamic visual interfaces is also introduced, and its propert…
Spectral scattering dependencies of controllable PLZT occluder for vision science applications
2001
Summary form only given. PLZT ceramics have an unique property - a facility to change the light scattering efficiency with the applied electric field. This effect is well manifested especially in the visible, just where the transparency windows of PLZT begins. Formerly we developed eye occlusion devices for vision science applications to introduce a dynamic decrease of the image contrast in stereovision tests. In future we plan to construct, using controllable scattering in PLZT, an eye simulator to study cataract caused retinal image quality reduction. The present work reports on spectral dependencies of such an eye occluder studied with the double optical integrated sphere technique.
Evaluation of visual-motor reaction time and quality of response in rugby sevens players after the application of a neurocognitive training programme
2019
This work proposes a neurocognitive training (NCT) programme that seeks to optimise the mechanisms of visual perception, the processing of information and decision making. Also, to evaluate the eff...
A social humanoid robot as a playfellow for vocabulary enhancement
2018
We introduce a system that exploits a Pepper humanoid robot acting as a playfellow in a word-play game. The robot can play a portmanteau game by directly interacting with children, and it exploits a conversation engine, a portmanteau creation engine, and a definition engine. The humanoid can play the role of either an answerer or a generator of new words.
