A humanoid robot under real-world environments usually hears mixtures of sounds, and thus three capabilities are essential for robot audition; sound source localization, separation, and recognition of separated sounds. While the first two are frequently addressed, the last one has not been studied so much. We present a system that gives a humanoid robot the ability to localize, separate and recognize simultaneous sound sources. A microphone array is used along with a real-time dedicated implementation of Geometric Source Separation (GSS) and a multi-channel post-filter that gives us a further reduction of interferences from other sources. An automatic speech recognizer (ASR) based on the Missing Feature Theory (MFT) recognizes separated sounds in real-time by generating missing feature masks automatically from the post-filtering step. The main advantage of this approach for humanoid robots resides in the fact that the ASR with a clean acoustic model can adapt the distortion of separated sound by consulting the post-filter feature masks. Recognition rates are presented for three simultaneous speakers located at 2m from the robot. Use of both the post-filter and the missing feature mask results in an average reduction in error rate of 42% (relative).

This article demonstrates results and experiences gained in the area of multilayer internetworking, with emphasis on bandwidth on-demand provisioning as well as resource and restoration management. Behavioral characteristics and numerical results were obtained from a management system prototype implemented and tested in an appropriately adapted commercial WDM environment enhanced with multivendor gigabit IP routers. The management solution, the testbed environment, and a representative evaluation scenario are presented as a means of explaining in detail the results that finally allow a global system assessment.

Distributed virtual reality: building a multi-user layer for the EVE Platform

引用

JOURNAL OF NETWORK AND computer APPLICATIONS 2004年第2期27卷 91-111页

作者： Bouras, C Tsiatsos, T Research Academic Computer Technology Institute Greece Computer Engineering and Informatics Department University of Patras Greece

dIn this paper, we present the design and implementation of a VRML97 multi-user layer, which is introduced in the EVE distributed virtual reality platform. Though other approaches use a VRML node insertion mechanism, Such as VSPLUS, or a substitution mechanism, Such as SPIN-3D, our approach uses a removal mechanism. Main consideration of our multi-user extension is the ease of transforming single-user virtual worlds into multi-user virtual worlds, as well as the conformity with any standard VRML97 browser. Furthermore, we present the EVE' s communication platform, which can be used in order to support Collaborative Virtual Environments. Main issues regarding the effective network communication as well as the initialization of the 3D scene are discussed in this paper. (C) 2003 Elsevier Ltd. All rights reserved.

This paper describes the robust reading competitions for ICDAR 2003. With the rapid growth in research over the last few years on recognizing text in natural scenes, there is an urgent need to establish some common benchmark datasets and gain a clear understanding of the current state of the art. We use the term 'robust reading' to refer to text images that are beyond the capabilities of current commercial OCR packages. We chose to break down the robust reading problem into three subproblems and run competitions for each stage, and also a competition for the best overall system. The subproblems we chose were text locating, character recognition and word recognition. By breaking down the problem in this way, we hoped to gain a better understanding of the state of the art in each of the subproblems. Furthermore, our methodology involved storing detailed results of applying each algorithm to each image in the datasets, allowing researchers to study in depth the strengths and weaknesses of each algorithm. The text-locating contest was the only one to have any entries. We give a brief description of each entry and present the results of this contest, showing cases where the leading entries succeed and fail. We also describe an algorithm for combining the outputs of the individual text locators and show how the combination scheme improves on any of the individual systems. © Springer-Verlag 2005.

We have established a medical network in Asia-Pacific area with high-quality moving image on a super broad-banded internet line since February 2003. Broadcasting real-time surgery and teleconference with medical-quality videos with Digital Video Transport System (DVTS) were so useful to learn surgical techniques and other medical procedures beyond borders. We have conducted 20 events in categories of teleconference (8 times), live transmission of medical procedure (6 times), and remote attendance to scientific medical meetings (6 times) until September 2004. We had teleconferences among 3 countries in APAN-Hawaii in January 2004 (Japan, Korea and USA), and in APAN-Cairns in July 2004 (Japan, Korea and Australia). There have been no serious transmission/ ethical problems sofar. With these experiences and current achievements, we hope to extend this advanced network system to whole Asia-Pacific countries to share medical skills and knowledge. © 2005 IEEE.

Approximate path coloring with applications to wavelength assignment in WDM optical networks

引用

21st Annual Symposium on Theoretical Aspects of computer Science, STACS 2004

作者： Caragiannis, Ioannis Kaklamanis, Christos Research Academic Computer Technology Institute Department of Computer Engineering and Informatics University of Patras Rio26500 Greece

Motivated by the wavelength assignment problem in WDM optical networks, we study path coloring problems in graphs. Given a set of paths P on a graph G, the path coloring problem is to color the paths of P so that no two paths traversing the same edge of G are assigned the same color and the total number of colors used is minimized. The problem has been proved to be NP-hard even for trees and rings. Using optimal solutions to fractional path coloring, a natural relaxation of path coloring, on which we apply a randomized rounding technique combined with existing coloring algorithms, we obtain new upper bounds on the minimum number of colors sufficient to color any set of paths on any graph. The upper bounds are either existential or constructive. The existential upper bounds significantly improve existing ones provided that the cost of the optimal fractional path coloring is sufficiently large and the dilation of the set of paths is small. Our algorithmic results include improved approximation algorithms for path coloring in rings and in bidirected trees. Our results extend to variations of the original path coloring problem arizing in multifiber WDM optical networks. © Springer-Verlag Berlin Heidelberg 2004.
