I n our modern society, distance education has become a viable solution for students who require more flexible, accessible, and adaptive teaching systems, without spatial and temporal restrictions , . In the past, the interaction methods for distance education were limited to the telephone, postal mail, or fax. Today's new information technologies… (More)
A pan-tilt structure has been endowed with the capability of doing the visual tracking of a moving target. Moving objects in the field of view of the camera are detected and the more relevant region colour feature is selected as the pattern to follow. Colour histogram is used as reliable feature to model object appearance and its adaptation handles with… (More)
Worldwide, there is increasing interest in the operation of multiple autonomous underwater vehicles (AUVs) to carry out scientific and commercial missions at sea. For some of the envisioned missions, it is crucial that new methods be developed to localize one more of the vehicles simultaneously, based on acoustic range information received on-board a set of… (More)
Smart-devices with information sharing capabilities anytime and anywhere have opened a wide range of ubiquitous applications. Within urban environments citizens have a plethora of locations to choose from, and in the advent of the smart-cities paradigm, this is the scope of location-based rec-ommender systems to provide citizens with the adequate… (More)
The objective of this paper is to evaluate the behaviour of a controller designed using a parametric Eigenstructure Assignment method and to evaluate its suitability for use in flexible spacecraft. The challenge of this objective lies in obtaining a suitable controller that is specifically designated to alleviate the deflections and vibrations suffered by… (More)
This article presents the topics in wheeled mobile robotics where the Learning and Vision Mobile Ro-botics Group (IRI) is focusing its efforts. The areas covered include robot localization, color in-variance, segmentation, tracking, audio processing and object learning and recognition. An overview of recent results produced in our group within these areas… (More)
Second-order random graphs for modelling sets of attributed graphs and their application to object learning and recognition.
This article presents the current trends on wheeled mobile robotics being pursued at IRI-UPC-CSIC. It includes an overview of recent results produced in our group in a wide range of areas, including robot localization, color invariance, segmenta-tion, tracking, visual servoing, and object and face recognition.
