Manual de boas prácticas ambientais : actividades portuárias

[ES]En este manual, editado en el marco del Proyecto ESTRAMAR (PCT-MAC 2007-2013, de los Fondos FEDER), se proponen una serie de directrices y objetivos medioambientales para las diferentes actividades portuarias, desarrollando así una labor de prevención y reducción de la contaminación de las mismas. El objetivo es desarrollar la sensibilización por el medio ambiente y el uso de los recursos de una manera sostenible y fomentar la participación de las empresas y los usuarios en la gestión medioambiental de los sistemas portuarios. Para ello, este manual hace hincapié en tres actividades portuarias concretas para las que exponen una serie de recomendaciones y buenas prácticas. Estas actividades son: la pesca, el transporte de mercancías, y las actividades industriales en astilleros.

Manual de boas prácticas: gestão das águas portuárias

[ES] En este manual, editado en el marco del Proyecto ESTRAMAR (PCT-MAC 2007-2013, de los Fondos FEDER), se proponen una serie de directrices y objetivos medioambientales para una correcta gestión de las aguas en los entornos portuarios, desarrollando así una labor de prevención y reducción de la contaminación de las mismas. El objetivo del manual es el de proponer una serie de medidas simples que, sin alterar la calidad de los servicios prestados, hacen posible minimizar los efectos de las actividades portuarias sobre sus aguas. Las buenas prácticas que se proponen incluyen medidas a poner en práctica en función del tipo de residuo que se genere, así como información sobre las aguas de lastre y los materiales de dragado.

Comparison of focus measures in face detection environments

[EN]This work presents a comparison among different focus measures used in the literature for autofocusing in a non previously explored application of face detection. This application has different characteristics to those where traditionally autofocus methods have been applied like microscopy or depth from focus. The aim of the work is to find if the best focus measures in traditional applications of autofocus have the same performance in face detection applications. To do that six focus measures has been studied in four different settings from the oldest to more recent ones.

Una propuesta de instalación basada en Habilidades de Visión por Computador

[ES]Se propone en este trabajo la utilización de habilidades de detección de personas basadas en Visión por Ordenador para su integración en instalaciones artísticas de vídeo, explorando someramente sus capacidades, y mostrando una propuesta preliminar.

Real-time detection of faces in video streams

[EN]This paper describes a face detection system which goes beyond traditional approaches normally designed for still images. First the video stream context is considered to apply the detector, and therefore, the resulting system is designed taking into consideration a main feature available in a video stream, i.e. temporal coherence. The resulting system builds a feature based model for each detected face, and searches them using various model information in the next frame. The results achieved for video stream processing outperform Rowley-Kanade's and Viola-Jones' solutions providing eye and face data in a reduced time with a notable correct detection rate.

CASIMIRO: a robot head for human-computer interaction

The physical appearance and behavior of a robot is an important asset in terms of Human-Computer Interaction. Multimodality is also fundamental, as we humans usually expect to interact in a natural way with voice, gestures, etc. People approach complex interaction devices with stances similar to those used in their interaction with other people. In this paper we describe a robot head, currently under development, that aims to be a multimodal (vision, voice, gestures,...) perceptual user interface.

Integrating an entertainment robot

[EN]In this paper we will present Eldi, a mobile robot that has been in opertation at the Elder Museum of Science and Technology at Las Palmas de Gran Canaria since december 1999. This is an ongoing project that was organized in three different stages of which only the first one has been accomplished. The initial phase, termed "The Player", the second stage, actually under develpment, has been called "The Cicerone" and in the final phase, termed "The Vagabond", in which Eldi will be allowed to move erratically across the Museum. This paper will focus on the accomplished first stage to succinctly describe the physical robot and the environment and demos developed. Finally we will summarize some important lessons learnt.

DESEO: an active vision system for detection, tracking and recognition

[EN]In this paper, a basic conceptual architecture aimed at the design of Computer Vision System is qualitatively described. The proposed architecture addresses the design of vision systems in a modular fashion using modules with three distinct units or components: a processing network or diagnostics unit, a control unit and a communications unit. The control of the system at the modules level is designed based on a Discrete Events Model. This basic methodology has been used to design a realtime active vision system for detection, tracking and recognition of people. It is made up of three functional modules aimed at the detection, tracking, recognition of moving individuals plus a supervision module.

An active vision system integrating fast and slow processes

[EN]This paper describes an Active Vision System whose design assumes a distinction between fast or reactive and slow or background processes. Fast processes need to operate in cycles with critical timeouts that may affect system stability. While slow processes, though necessary, do not compromise system stability if its execution is delayed. Based on this simple taxonomy, a control architecture has been proposed and a prototype implemented that is able to track people in real-time with a robotic head while trying to identify the target. In this system, the tracking module is considered as the reactive part of the system while person identification is considered a background task.

Real-time tracking system using C80 DSPs and a binocular robotic head

[EN]An active vision system to perform tracking of moving objects in real time is described. The main goal is to obtain a system integrating off-the-self components. These components includes a stereoscopic robotic-head, as active perception hardware; a DSP based board SDB C80, as massive data processor and image acquisition board; and finally, a Pentium PC running Windows NT that interconnects and manages the whole system. Real-time is achieved taking advantage of the special architecture of DSP. An evaluation of the performance is included.

A C80 DSP-based active vision system for real-time tracking

[EN]Active Vision Systems can be considered as dynamical systems which close the loop around artificial visual perception, controlling camera parameters, motion and also controlling processing to simplify, accelerate and do more robust visual perception. Research and Development in Active Vision Systems [Aloi87], [Bajc88] is a main area of interest in Computer Vision, mainly by its potential application in different scenarios where real-time performance is needed such as robot navigation, surveillance, visual inspection, among many others. Several systems have been developed during last years using robotic-heads for this purpose...
