Pics 'n' Trails: an Open Multimedia Dataset for Lifelog Research

摘要

We present a large collection of location based life-log data that is publicly available for research. The Pics 'n' Trails dataset contains location data and digital photos captured by a single person over a period of more than a year. The location data were captured by continuously carrying a GPS receiver and recording the location coordinates at all times when they can be estimated. The photos, 4179 in total, were taken during sightseeing and other events. This paper describes the data collection, and our experiences in archiving and preparing the data set. It also summarizes two applications that have been built over this data set.
