A Japanese computer-assisted facial identification system successfully identifies non-Japanese faces
Fraser NL Yoshino M Imaizumi K Blackwell SA Thomas CD Clement JG 《Forensic science international》2003,135(2):122-128
The method developed by Yoshino et al. in [Forensic Sci. Int. 109 (2000) 225 and Jpn. J. Sci. Tech. Iden. 5 (2000) 9] and already being applied in Japan utilizes a three-dimensional (3D) physiognomic rangefinder combined with a computer-assisted superimposition system. Facial outlines can be compared between two-dimensional (2D) surveillance images and data extracted from 3D images obtained from the rangefinder. Also, the loci of potentially concordant features can be compared and differences measured. The method is largely objective and gives statistics for false positive/false negative findings. This recently developed method by Yoshino et al. is currently being introduced to the Japanese courts. To enable courts outside Japan to assess the admissibility of this new method, studies of non-Japanese faces have been undertaken and shown to produce similar low error rates. The present authors, therefore, consider the Yoshino method to be applicable in a non-Japanese context. As part of this study a comparison of morphological features between two ethnic groups has been undertaken using 3D measurements for the first time and will serve as the foundation for an anthropological database in the future. 相似文献

This study is interested in the impact of Facebook as a source for political information on public opinion during political controversies. In a society where the mainstream media are under heavy influence by the dominant power and yet Internet communication is largely open and free, social media may become particularly important for the transmission of critical information and viewpoints. The social media information environment may exhibit an overall ‘anti-establishment bias.’ However, the impact of social media should vary across individuals depending on the extent and character of user selectivity. Analysis of data collected during the political reform debate in Hong Kong (N?=?3,246) show that reliance on Facebook as an information source relates negatively to support for the government’s reform proposal. But the relationship is strongest for people without a strong political orientation and people who do not name any newspapers as their main information source. General theoretical implications of the findings are discussed. 相似文献

The identification of individuals, particularly at international border crossings, coupled with the evolving sophistication of identity documents are issues that authorities must contend with. Particularly, the ability to distinguish legitimate from counterfeit documents, with high throughput, sensitivity, and selectivity is an ever-evolving challenge.Over the last decade, an increasing number of security features have been introduced by authorities in identification documents. The latest generation of travel documents (such as passports and national ID cards) forego paper substrates for several layers of polycarbonate, allowing security features to be embedded within the documents. These security features may contain information at either the superficial and sub-surface levels, thus increasing the document’s resilience to counterfeiting.As the documents become harder to forge, so does the sophistication of forgery detection. There appears to be an unmet and evolving need to identify such sophisticated forgeries, in a non-destructive, high throughput manner.In this publication, we report on the application of optical coherence tomography (OCT) imaging on assessing security features in specimen passports and national ID cards. OCT allows sub-surface imaging of translucent structures, non-destructively enabling quantitative visualisation of embedded security features. 相似文献

Abstract Southeast Asian refugees have been arriving in the U.S. in significant numbers since 1975. While they have had a history of a seemingly smooth resettlement and acculturation to this country, the number of Southeast Asian youthful offenders has increased dramatically since 1984. Factors common among refugee youth which have contributed to this rise include: problems of acculturation; role reversal with parents; lack of shared values, parental guidance and school success; and mental health problems often stemming from their history of war, traumatization, and loss before coming to this country. This article will discuss these factors and the implications for the juvenile justice system. The discussion will also highlight culturally appropriate intervention strategies for personnel working with these youth and their families. 相似文献

The reliability of a morphometrical matching method for identifying disguised faces was examined experimentally using a computer-assisted facial image identification system. The 2D right oblique facial images of three target persons disguised with sunglasses, cap and gauze mask were each compared with each of the 3D facial images of 100 subjects, yielding 900 face-to-face superimpositions. The average perpendicular distance between the facial outlines and the average point-to-point distance of the corresponding landmarks in the 2D image of the disguised face and the 3D facial image, were calculated. As a matching criterion, the sum of the values of the average perpendicular difference of the facial outlines and the average point-to-point difference between the corresponding landmarks was used (abbreviation: average difference).The range of the average difference was 2.3-2.8mm for the same person (a match) and 4.0-14.6mm for different (non-matching) people, respectively. The ranges for matching and non-matching faces did not overlap. Even the 3D facial images of the non-matching person showing the closest value of average difference to the average difference for the matching person could be excluded easily. It was concluded that the morphometrical matching method can reliably identify disguised faces and the results produced by this method could be easily understandable by a court of law. 相似文献

AbstractIn this article, I examine the bias in favour of financial markets displayed by the European Central Bank (ECB) during the Eurozone crisis. Having analysed the roots of the ECB’s bias, I explore the discrepancy between the conditionality of ECB financial support that is directed towards states and that which is directed towards markets. On the one hand, the ECB has exerted strong coercive and cognitive pressures to reform Eurozone economic governance in a market-friendly way. On the other hand, it has employed monetary measures to save large Eurozone banks from a complete meltdown without controlling how these banks use their provided liquidities. I conclude by stressing the democratic problems engendered by the ECB’s bias. 相似文献
