A new retrieval system for a 3D facial image database was designed and its reliability was experimentally examined. This system has two steps, firstly to automatically adjust the orientation of all 3D facial images in a database to that of the 2D facial image of a target person, and then to identify the facial image of the target person from the adjusted 3D facial images in the database using a graph-matching method. From the experimental study [M. Yoshino, K. Imaizumi, T. Tanijiri, J.G. Clement, Automatic adjustment of facial orientation in 3D face image database, Jpn. J. Sci. Tech. Iden. 8 (2003) 41-47], it is concluded that the software developed for the first step will be applicable to the automatic adjustment of facial orientation in the 3D facial image database. In 28 out of 110 sets (25.5%), the 3D image of the target person was chosen as the best match (from a database of 132 3D facial images) according to the similarity of the facial image characteristics based on the graph matching. The 3D facial image of the target person was ranked in the top of 10 of the database in 75 out of 110 sets (68.2%). These results suggest that this system is inadequate for the identification level, but may be feasible for screening method in a small database. It will be necessary to further pursue the possibility of realization of a facial image retrieval system for a large database such as suspects' facial images in future.  相似文献

Abstract: The objective of this article is to analyse public initiatives to stimulate regional innovation in Walloon region in Belgium and in the Province of Quebec. The empirical analysis relies on the competitive poles program in Walloon and on the ACCORD project (Action Concertée de Coopération Régionale de Développement) in Quebec. The comparison will allow discussing the implementation and regional embedding of these programs and will reveal the similarities and the differences between the structure, the organization and the deployment of these strategies in the various regions targeted.  相似文献

In Lebanon, the fear of taw?īn makes nationalization of Palestinian refugees an anathema. Yet several groups of Palestinians have received Lebanese citizenship since 1948, most (in)famously those from the ‘seven villages’, a chain of Shi‘i villages on Lebanon's southern border that was incorporated into Palestine in 1923. The trajectory of their nationalization is usually presented as a straightforward consequence of top-down Lebanese electoral politics. This article augments this dominant perspective through a case study of the community from the village of Salha, now in Israel, that currently lives in Shabriha, a small town near the city of Tyre in South Lebanon. Adopting the ‘negotiated statehood’ framework, the article offers an agency-oriented, bottom-up perspective on the community's gaining of citizenship and shows how the people from Salha have acquired citizenship not merely to gain access to, but also to ensure a degree of independence from, the Lebanese state and political parties.  相似文献

Business Development Services (BDS) programmes have become big business for international donors and NGOs. Focusing on small enterprises in developing countries, the current BDS approach assumes that the development of commercial markets is the key to success. Yet many of these programmes continue to have a limited impact. A review of modern theories of innovation and services marketing management suggests that this may be because current BDS support practice reflects a rather limited understanding of how new markets actually develop. Drawing on the insights that these theories offer, the authors suggest that BDS practice should develop a more evolutionary approach, recognising that service innovations develop through active, on-going interaction between suppliers and customers. The article concludes with practical policy guidelines and a discussion about tools that could help BDS to adopt this more successful approach.  相似文献

This article examines how two of Japan’s largest newspapers frame death penalty issues. Through a content analysis of 7,153 Asahi and Nikkei articles in the 66-month period from January 1, 2007 to June 30, 2012, 11 death penalty frames are identified: inevitability, atonement by dying, atonement by living, victims’ rights and emotions, human rights, miscarriage of justice, calls for discussion, life without parole, deterrence, public support, and retribution. In addition to frames, we examined who the main voices are in each article on capital punishment. We found that avoidance and ambivalence are the two main approaches taken by Asahi and Nikkei to cover death penalty issues, and the most surprising finding is the high salience of atonement as a frame for thinking about capital punishment. In Japan, atonement is used to justify (atone by dying) and oppose (atone by living) the death penalty. Although atonement by living in prison and atonement by dying at the gallows imply radically different outcomes, the flexibility of the atonement frame may suggest new possibilities for Japan’s anti-death penalty movement.  相似文献
