人工智能论文:PVSS:用于视频监控网络的渐进式车辆搜索系统(PVSS: A Progressive Vehicle Search System for Video Surveillance  Networks)本文的重点是搜索监控网络中出现的特定车辆。现有方法通常假设从监控视频中很好地裁剪车辆图像,然后使用视觉属性,如颜色和类型,或车牌号码来匹配图像集中的目标车辆。然而,完整的车辆搜索系统应该考虑车辆检测,表示,索引,存储,匹配等问题。此外,基于属性的搜索由于不同摄像机的内部变化和极不确定的环境而无法准确找到相同的车辆。此外,由于低分辨率和噪声,车牌可能在监视场景中被识别。在本文中,设计了一种名为PVSS的渐进式车辆搜索系统来解决上述问题。 PVSS由三个模块组成:爬虫,索引器和搜索器。车辆爬行器旨在检测和跟踪监视视频中的车辆并将捕获的车辆图像,元数据和上下文信息传送到服务器或云。然后由车辆索引器提取和索引多粒度属性,例如视觉特征和车牌指纹。最后,将具有输入车辆图像,时间范围和空间范围的查询三元组作为车辆搜索者的输入。将通过渐进过程在数据库中搜索目标车辆。来自真实监控网络的公共数据集的广泛实验验证了PVSS的有效性。
This paper is focused on the task of searching for a specific vehicle thatappeared in the surveillance networks.Existing methods usually assume thevehicle images are well cropped from the surveillance videos, then use visualattributes, like colors and types, or license plate numbers to match the targetvehicle in the image set.However, a complete vehicle search system shouldconsider the problems of vehicle detection, representation, indexing, storage,matching, and so on.Besides, attribute-based search cannot accurately find thesame vehicle due to intra-instance changes in different cameras and theextremely uncertain environment.Moreover, the license plates may bemisrecognized in surveillance scenes due to the low resolution and noise.Inthis paper, a Progressive Vehicle Search System, named as PVSS, is designed tosolve the above problems.PVSS is constituted of three modules: the crawler,the indexer, and the searcher.The vehicle crawler aims to detect and trackvehicles in surveillance videos and transfer the captured vehicle images,metadata and contextual information to the server or cloud.Then multi-grainedattributes, such as the visual features and license plate fingerprints, areextracted and indexed by the vehicle indexer.At last, a query triplet with aninput vehicle image, the time range, and the spatial scope is taken as theinput by the vehicle searcher.The target vehicle will be searched in thedatabase by a progressive process.Extensive experiments on the public datasetfrom a real surveillance network validate the effectiveness of the PVSS.人工智能论文:PVSS:用于视频监控网络的渐进式车辆搜索系统(PVSS: A Progressive Vehicle Search System for Video Surveillance  Networks) ahes4TW6H7H3ee3C.jpg
