The appearance attribute and pose are two important and complementary features, so integrating them can effectively alleviate the impact of misalignment and occlusion on re-identification. In this paper, we deeply investigate the inner relation between attribute features and the spatial semantic relation between key-point region features of the pose in a person image and propose a person re-identification method based on discriminative feature mining with relation regularization. Firstly, an attribute relation detector based on nonlinear graph convolution is built on mining the inner correlation between attribute features of a person, providing relational attribute features for more effectively distinguishing persons with a similar appearance. Then, we construct a hierarchical pose pyramid to model the multi-grained semantic features of key-point regions of the pose and propose intra-graph and cross-graph node relation information propagation structures to infer the spatial semantic relation between node features within-graph and between-graph. This module is robust to complex pose changes and can suppress noise background redundancy caused by inaccurate key point detection and occlusion. Finally, a refined feature model is proposed to effectively fuse the global appearance feature with the relational attribute and multi-grained pose features, thus providing a more discriminative fusion feature for person re-identification. Many experiments on three large-scale datasets verify the effectiveness and state-of-the-art performance of the proposed method. 相似文献

On knowledge-poor methods for person name matching and lemmatization for highly inflectional languages 总被引：1，自引：1，他引：0
Web person search is one of the most common activities of Internet users. Recently, a vast amount of work on applying various
NLP techniques for person name disambiguation in large web document collections has been reported, where the main focus was
on English and few other major languages. This article reports on knowledge-poor methods for tackling person name matching
and lemmatization in Polish, a highly inflectional language with complex person name declension paradigm. These methods apply
mainly well-established string distance metrics, some new variants thereof, automatically acquired simple suffix-based lemmatization
patterns and some combinations of the aforementioned techniques. Furthermore, we also carried out some initial experiments
on deploying techniques that utilize the context, in which person names appear. Results of numerous experiments are presented.
The evaluation carried out on a data set extracted from a corpus of on-line news articles revealed that achieving lemmatization
accuracy figures greater than 90% seems to be difficult, whereas combining string distance metrics with suffix-based patterns
results in 97.6–99% accuracy for the name matching task. Interestingly, no significant additional gain could be achieved through
integrating some basic techniques, which try to exploit the local context the names appear in. Although our explorations were
focused on Polish, we believe that the work presented in this article constitutes practical guidelines for tackling the same
problem for other highly inflectional languages with similar phenomena.

This paper reviews the role of the Designated Liaison Person (DLP) for Child Protection in the Irish primary school context. This is a role assigned by the Board of Management to a person in the school who oversees all matters pertaining to child protection including reporting abuse, liaising with staff and outside agencies in relation to child protection and meeting parents as required. Given the responsibilities associated with the role, it is normally the Principal teacher in the school who undertakes the role. A study undertaken with a number of DLPs in a variety of schools of different size and type highlights the multifaceted nature of the role, the supports available to DLPs and the challenges in undertaking this responsibility. The responsibility of ensuring the DLP is taking the correct course of action in making a referral of abuse in relation to a child is highlighted in the findings. Recent updates in child protection legislation which will impact on child protection procedures and policy in the school environment are also considered in this paper. 相似文献

目的：以“中国数字人男一号”CT图像、MRI图像为研究素材,对同一人体同期CT图像与MRl图像进行融合,并对融合效果进行比较评价。在此基础上实现同期CT图像与MRI图像的三维融合重建图像。方法：首先介绍小波变换图像融合方法、算法、图像融合过程与步骤;然后对CT图像进行骨骼组织分割;其次,通过使用图像预处理及二维空间变换处理,解决两种骨骼组织分割图像参数差异较大的问题;最后,对这两种模式的骨骼组织分割图像在配准的基础上进行融合,并给出融合结果。结果：实现了CT图像和MRI图像的二维空间融合及三维重建。结论：小波变换图像融合方法对常用的CT／MRI图像融合及三维重建是一种有效的方法。 相似文献

Specific stereotype portrayals of African American women were hypothesized to produce stereotype-consistent judgments made of a different African American woman. Participants (N?=?76) observed a mammy, jezebel or welfare queen video-segment. Then they observed an African American woman in a mock job interview and rated the interviewee. Participants who observed a specific stereotype associated the interviewee more quickly with stereotype-consistent adjectives than with stereotype-inconsistent adjectives for all three stereotypes. For measures of how suitable the woman was for jobs that were related to the stereotypes, only the welfare queen prime produced significant effects. 相似文献
