基于非动作分类的人体动作识别方法

Improving Human Action Recognition by Non-action Classification

Stony Brook University(石溪大学)

Yang Wang, Minh Hoai

摘要:

在本文中,我们认为,在现实的视频中,人类的行动是由不相关的因素占主导地位的识别人类的行动的任务。我们首先研究删除非动作视频片段的好处,这些片段不描绘任何人类动作。然后,我们学习一个非动作分类器,并使用它来降低不相关视频片段的权重。非动作分类器是使用NATIONAL Thread训练的,NATIONAL Thread是一个具有镜头级注释的数据集,用于人类动作的发生或不发生。非动作分类器可用于以高精度识别非动作镜头,并随后用于提高动作识别系统的性能。

英文摘要:

In this paper we consider the task of recognizing human actions in realistic video where human actions are dominated by irrelevant factors. We first study the benefits of removing non-action video segments, which are the ones that do not portray any human action. We then learn a non-action classifier and use it to down-weight irrelevant video segments. The non-action classifier is trained using ActionThread, a dataset with shot-level annotation for the occurrence or absence of a human action. The non-action classifier can be used to identify non-action shots with high precision and subsequently used to improve the performance of action recognition systems.
