摘要

生活日志搜索挑战赛(LSC)于2018年首次在日本横滨举行,是一项交互式生活日志内容检索竞赛,国际团队面临着在大量多模式生活日志数据中寻找特定时刻的任务。作为成功参加LSC2018的团队之一(第二名),我们在第二次挑战中展示了我们改进的lifeXplore系统。lifeXplore系统基于diveXplore(一种为年度视频浏览器对决而开发的交互式视频检索系统),类似地对拍摄分段视频数据进行操作,同时维护可浏览的特征地图并提供可定制的相似性搜索,同时还引入了元数据过滤和交互式日检查等附加功能。除了几项较小的功能和可用性改进外,LSC2019版本的系统还特别包括可组合过滤器、基于地理位置的过滤和自动特征地图浏览,以改善用户的搜索和浏览体验。

lifeXplore at the Lifelog Search Challenge 2019
First held in Yokohama, Japan in 2018, the Lifelogging Search Challenge (LSC) is an interactive lifelogging content retrieval competition, where international teams are faced with the task of finding specific moments within a large collection of multimodal lifelogging data. As one of the successfully participating LSC2018 teams (2nd place), we present our improved lifeXplore system for the second iteration of this challenge. Based on diveXplore, an interactive video retrieval system that has been developed for the annual Video Browser Showdown, the lifeXplore system similarly operates on shot-segmented video data, while maintaining browseable feature maps and offering customizable similarity search, yet also introducing additional features such as metadata filtering and interactive day inspection. Alongside several smaller functionality and usability improvements, the LSC2019 version of the system in particular includes combinable filters, geolocation-based filtering and automatic feature map browsing in order to improve a user's searching and browsing experience.
