Highlights Extraction Method For Soccer Video Based On Exciting Degree

In recent years, the processing and retrieval of soccer video is increasingly rapid developing and has become a hotspot. Although soccer video last for a long time, there are only a few highlights which the viewers just want to watch directly inside it. How to exactly extract highlights is an important step in the research of soccer video.Based on the analysis of massive computation and the fixed highlights type of the existed extraction methods, a highlights extraction technique, named Exciting Degree-based Highlights Extraction Method, is proposed. Exciting Degree includes audio exciting degree and visual exciting degree. Audio exciting degree is computed by the ratio for the number of the frames whose features meet the needs in the whole soccer video. The highlights are followed by a few scenes, for example the short scene and the player scene. The visual exciting degree is summation of the frame type value for these shots. The proposed approach computes audio exciting degree using the features of audio short-term energy and zero crossing rates to extract the candidate highlights, and uses frame classification to compute the visual exciting degree for highlights verification.Experimental results indicate that the proposed method extracts the highlights efficiently. However, only a few types of exciting degree are designed for audio and visual information. How to accurately calculate the audio exciting degree and the visual exciting degree is our future research emphasis.
