Abstract

This paper proposes a novel approach to replay detection in sports video. The proposed method consists of efficient semi-automatic logo template sequence extraction and logo template sequence based replay detection. In the beginning, two video segments are marked manually. Then a logo template sequence extraction algorithm is adopted to extract logo template sequence automatically. Once the logo sequence is extracted, the sequence is used to locate the replay segments accurately by the template sequence matching method. The experiments are carried out on various types of sports videos. The experimental results show that our algorithm can extract logo template sequence accurately and detect replays effectively. Moreover, our algorithm is generic and easy to use.
