A Topological Data Analysis Approach to Video Summarization

Chuan-Shen Hu, Mei-Chen Yeh

Abstract: This paper explores the use of simplicial complex to construct a new structure-wise representation for videos. Complementary to the appearance-based representation, which usually involves feature extraction from video content, the proposed method captures the structural properties of a video and can be used for various video processing tasks. We demonstrate a case study of the proposed approach to automated video summarization, which relies only on the developed topological structures and requires no training phase. Experimental results show the potential of this approach to facilitate tasks involving the understanding and analysis of structural information inherent in videos.
