Person re-identification aims to match people across non-overlapping camera views, which is an important but challenging task in video surveillance. In order to obtain a robust metric for matching, metric learning has been introduced recently. Most existing works focus on seeking a Mahalanobis distance by employing sparse pairwise constraints, which utilize(More)
According to the deficiency that existed in traditional design mode of production line and the fact that the federate ambassador callback between the LRC(local RTI) and the CRC(central RTI) can hardly pass through firewalls in grid when using HLA (High Level Architecture), this paper puts forward a service-oriented and HLA-based simulation model of juice(More)
Interaction among users in the context of collaborative virtual environments (CVEs) affects the efficiency of collaborative work. In most of the current CSCW application systems, users' interaction is still based on the traditional ways such as typed chat and so on. In order to enrich the interaction among users, someone has proposed to add 3D avatars into(More)
Version management of CSCD is supposed to support the whole design progress and store all versions produced in the process to be available for request. Two difference storage models are proposed based on analysis and study on full storage and difference storage patterns in terms of version information. Full storage has characteristics of fast storage and(More)
Most of the existing works on person re-identification have focused on improving matching rate at top ranks. Few efforts are devoted to address the problem of efficient storage and fast search for person re-identification. In this paper, we investigate the prevailing hashing method, originally designed for large scale image retrieval, for fast person(More)
In this working note, we mainly focus on the image annotation subtask of ImageCLEF 2015 challenge that BUAA-iCC research group participated. For this task, we firstly explore textual similarity information between each test sample and predefined concept. Subsequently , two different kinds of semantic information are extracted from visual images: visual tags(More)
Video-based person re-identification has become a hot topic in the field of research on computer vision and intelligent surveillance, which is more robust to the variations in a person's appearance than single-shot based methods and involves space-time information. However, the most existing spatiotemporal features have been proposed for action recognition(More)
