Pyramidwise Structuring for Soccer Highlight Extraction

چکیده
Fast browsing video contents not only is an important research issue, but also has a variety of potential applications, especially for sports videos. In this paper, we propose a practical solution to extract highlights from soccer videos, which is based on the structure analysis of broadcast soccer video. First, the broadcast soccer video is structured into a soccer pyramid composing a series of layers from fine to coarse. With such a soccer pyramid structure, soccer highlights can be extracted in a flexible manner according to different high-level applications. Besides, in order to obtain soccer pyramid, a condensation approach to soccer video and the corresponding structure extraction methods are also proposed to achieve pyramidwise structuring. Experiments have demonstrated the effectiveness, efficiency and robustness of the proposed approach to structuring and highlight extraction.

Detection of goal events in soccer videos
In this paper, we present an automatic extraction of goal events in soccer videos by using audio track features alone without relying on expensive-to-compute video track features. The extracted goal events can be used for high-level indexing and selective browsing of soccer videos. The detection of soccer video highlights using audio contents comprises three steps: 1) extraction of audio featur...

In this paper, a fast highlight detection and scoring method is proposed using an ondemand feature extraction and a fuzzy inference system. The proposed method partitions video to highlights and analyzes their content using an on-demand feature extraction approach. Then, a score is assigned to each highlight using a Fuzzy Inference System (FIS) according to the analyzed content. The assigned sc...

In this paper, we present a novel methodology for sports highlight detection based on audio information. For processing the sounds of sports events, we propose a timefrequency feature extraction method computing local autocorrelations on complex Fourier values (FLAC). For highlights detection, we apply (complex) subspace method to the extracted FLAC features to detect the “exciting” scenes whic...

متن کاملHighlight Summarization in Soccer Video based on Goalmouth Detection
Highlight summarization technology has been widely investigated in sports videos. In this paper, we propose a specific method for highlight summarization in soccer video based on goalmouth frames detection and audio energy ranking. Firstly, we extract the video clips which contain the goalmouth area as the highlight candidates. Then, based on the commonsense that the volume and the length of th...
