摘要	Vision based event analysis plays a very critical role in automatically organizing user generated photos. It is difficult because of the following challenges. (1) Intra-class variation. Photos uploaded by users are sparsely sampled visual appearances of event over time. Thus, each photo may only capture a single object or scene of a specific complex event. (2) Inter-class confusion. Photos related to different events may contain similar objects or scenes. (3) For abnormal event, it has sample scarcity issue and only few samples can be used for event pattern learning. In this paper, by considering the photo taken time, we propose a novel structured event modeling (SEM) framework for event analysis by exploiting temporal information of visual features and event classes in photo sequence. More specifically, the temporal event patterns of the photo sequence and the relationship of different photos are learned jointly through deep neural networks (CNNs and RNNs) and conditional random field (CRF). We evaluate the proposed structured event modeling framework in two applications including the mutliclass event recognition and abnormal event discovery in photo sequence. The extensive experimental results on a public event recognition dataset and a collected abnormal event dataset demonstrate the effectiveness of the proposed method.
