Real-time human action recognition on an embedded, reconfigurable video processing architecture

Copyright @ 2008 Springer-Verlag.In recent years, automatic human motion recognition has been widely researched within the computer vision and image processing communities. Here we propose a real-time embedded vision solution for human motion recognition implemented on a ubiquitous device. There are three main contributions in this paper. Firstly, we have developed a fast human motion recognition system with simple motion features and a linear Support Vector Machine (SVM) classifier. The method has been tested on a large, public human action dataset and achieved competitive performance for the temporal template (eg. “motion history image”) class of approaches. Secondly, we have developed a reconfigurable, FPGA based video processing architecture. One advantage of this architecture is that the system processing performance can be reconfiured for a particular application, with the addition of new or replicated processing cores. Finally, we have successfully implemented a human motion recognition system on this reconfigurable architecture. With a small number of human actions (hand gestures), this stand-alone system is performing reliably, with an 80% average recognition rate using limited training data. This type of system has applications in security systems, man-machine communications and intelligent environments.DTI and Broadcom Ltd

Assessing competitiveness: how firm-level data can help

As policymakers refocus on growth, the ability to take a firm-level view is key to disentangling the various factors at the root of competitiveness, and thus to designing appropriate policies. â?¢ Firm-level data provides critical information for the design of appropriate competitiveness measures that complement traditional macro analysis. â?¢ More work remains to be done assembling firm-level information, but the variance of the distribution of firm characteristics already conveys important information in addition to standard averages. â?¢ New indicators should be developed to translate the distribution of firm characteristics into indicators of competitiveness designed to capture not only average performance but also the heterogeneity of firm performance. This Policy Contribution builds on ongoing research within EFIGE (www.efige.org), a project to help identify the internal policies needed to improve the external competitiveness of the European Union.

Firm Assets and Investments in Open Source Software Products

Open source software (OSS) has recently emerged as a new way to organize innovation and product development in the software industry. This paper investigates the factors that explain the investment of profit-oriented firms in OSS products. Drawing on the resource-based theory of the firm, we focus on the role played by pre-OSS firm assets both upstream and downstream, in the software and the hardware dimensions, to explain the rate of product introduction in OSS. Using a self-assembled database of firms that have announced releases of OSS products during the period 1995-2003, we find that the intensity of product introduction can be explained by a strong position in software technology and downstream market presence in hardware. Firms with consolidated market presence in proprietary software and strong technological competences in hardware are more reluctant to shift to the new paradigm. The evidence is stronger for operating systems than for applications. The fear of cannibalization, the crucial role of absorptive capacity, and complementarities between hardware and software are plausible explanations behind our findings.Product Introduction, Open Source Software, Absorptive Capacity

Adopting interoperability solutions for online tourism distribution

This document is the Accepted Manuscript version of the following article: Sofia Reino, Aurkene Alzua-Sorzabal, Rodolfo Baggio, "Adopting interoperability solutions for online tourism distribution: An evaluation framework", Journal of Hospitality and Tourism Technology, Vol. 7(1): 2-15, January 2016. The final, published version is available online at https://doi.org/10.1108/JHTT-08-2014-0034. Published by Emerald Group Publishing Limited.Purpose – The purpose of this study is to identify the factors that make the adoption of interoperability solutions for online tourism distribution (OTD) more likely by small operators and to develop an evaluation framework for this solutions. Research identifying these determinants is missing. The resulting evaluation framework is then applied to evaluate a number of extant technological solutions focused on interoperability solutions for OTD. Design/methodology/approach – In an attempt to address this gap of research, this paper undertakes a series of interviews and focus groups of the European tourism industry. Findings – Findings partly aligned with the suggestion made by previous research about technology adoption by micro, small and medium tourism enterprises (SMTEs), they also highlighted some issues which are specific to the adoption of interoperability solutions for OTD. These related to the scarcity of information and communication technology (ICT) applications specifically designed for mini and micro enterprises, the very limited capabilities available for using efficiently ICTs in business-to-business (B2B) operations and the difficulty in collaborating with other companies due to the number of different solutions used in the industry, especially when dealing with large aggregators (global distribution systems (GDSs) or large online travel agencies) and lack of standardization for data. Research limitations/implications – The study has important theoretical implications. It provides a better understanding of issues affecting the adoption of interoperability solutions for OTD by SMTEs, such as the scarcity of ICT applications specifically designed for mini and micro enterprises, the very limited capabilities available for using ICTs efficiently in B2B operations and lack of standardization. Practical implications – It facilitates making decisions about adopting interoperability solutions for online distribution solutions, both by suppliers and destination managers. Originality/value – Limited work has focused on understanding issues affecting the adoption of interoperability solutions for OTD solutions among SMTEs.Peer reviewedFinal Accepted Versio

Transaction Streams: Definition and Implications for Trust in Internet-Based Electronic Commerce.

In this paper we analyze how transactions related to the exchange of goods and services are being performed on the Internet. The adoption of electronic markets in an industry has a disintermediation potential because it can create a direct link between the producer and the consumer (without the need for the intermediation role of distributors). Electronic markets lower the search cost, allowing customers to choose among more providers (which ultimately reduces both the costs for the customer and the profits for the producer). In this paper we contend that electronic markets on the Internet have the opposite effect, resulting in our increase in the number of intermediators. We introduce transaction streams, which model how transactions are being conducted and help explain the types of new intermediators that are appearing on the Internet. We also describe mechanisms by which companies are exploring ways of extending transaction streams. To illustrate the model and validate our findings, we analyze transaction streams in the insurance industry and review associated concepts such as trust and brands.transactions; electronic markets;

Underwater intervention robotics: An outline of the Italian national project Maris

The Italian national project MARIS (Marine Robotics for Interventions) pursues the strategic objective of studying, developing, and integrating technologies and methodologies to enable the development of autonomous underwater robotic systems employable for intervention activities. These activities are becoming progressively more typical for the underwater offshore industry, for search-and-rescue operations, and for underwater scientific missions. Within such an ambitious objective, the project consortium also intends to demonstrate the achievable operational capabilities at a proof-of-concept level by integrating the results with prototype experimental systems

Financing obstacles and growth: an analysis for euro area non-financial corporations

This paper investigates whether financial obstacles, and, more generally, financial pressure faced by firms, significantly affect firm growth. For this purpose, we use an unbalanced panel of about 1,000,000 observations for around 155,000 non-financial corporations in five euro area countries. In addition to the balance sheet information in this panel, we also rely on firm-level survey data. In this way we are able to work out a direct measure of the firms’ probability of facing financing obstacles. Our results indicate that, though based on few variables, this measure appears to be relevant in explaining firm growth in four out of the five countries considered. Other firm-level variables related to the financial pressure faced by firms, such as cash flow (debt burden) are found to exert a positive (negative) impact on firm growth, while the results for leverage are less clear-cut.
