In this paper, we propose an efficient scheme for automatically detecting highlight scenes in soccer videos. Highlights are defined as shooting scenes and goal scenes. Through the analysis of soccer videos, we notice that most of highlight scenes are shown around the goal post area. It is also noticed that the TV camera zooms in a setter player or spectators after the highlight stones. Detection of highlight scenes for soccer videos consists of three steps. The first step is the extraction of the playing field using a statistical threshold. The second step is the detection of goal posts. In the final step, we detect a zooming of a soccer player or spectators by using connected component labeling of non-playing field. In order to evaluate the performance of our method, the precision and the recall are computed. Experimental results have shown the effectiveness of the proposed method, with 95.2% precision and 85.4% recall.

This study sought to provide basic data on the soccer shoe brand strategy method by verifying the effectiveness of the soccer shoe brand 3i model to derive the importance and implications of the brand 3i model. Therefore, the sample was selected for those who have purchased soccer shoes for the past three years, and 421 copies of the data were applied to the final analysis. Data processing performed frequency analysis, internal consistency, confirmatory factor analysis, correlation analysis, and structural equation model analysis, all of which utilized SPSS (ver. 21.0) and AMOS (ver. 20.0) programs. The conclusions of this study are as follows. First, soccer shoe brand 3i model had a significant influence on brand trust. Second, brand trust had a significant influence on consumer purchasing behavior. Third, soccer shoe brand 3i model had a significant influence on consumer purchasing behavior. Lastly, brand trust between soccer shoe brand 3i model and consumer purchasing behavior showed partial mediated effect.

본 논문에서는 방송영상 특성을 이용한 축구 경기 장면 분석을 제안한다. 동영상의 프레임들을 분할하기 위해서는 급격한 장면 변화나 화면의 색상과 같은 화면의 형식적인 변화가 주요 결정사항이다. 그러나 축구경기와 같은 동영상에서의 하이라이트는 화면의 형식적인 변화와는 조금 다른 의미를 가진다. 그러므로, 축구 경기 동영상에서 하이라이트 부분을 검출하기 위해서는 장면의 변화와 더불어 화면의 의미를 해석할 필요가 있다. 본 논문에서는 축구 경기 동영상의 모든 프레임을 순차적으로 검사한다. 임의의 프레임에 대하여 RGB 정보의 분석을 통하여 영상의 구성내용을 파악한 후, 구성 내용의 위치와 분포를 참조하여 하이라이트 여부를 판단한다. 제안된 방법에서는 RGB 값의 변화 문제를 해결하기 위하여, 주 RGB 범위 군집화(Dominant RGB Grouping) 방법을 통하여 임의의 영상에서 RGB 값의 변화에 최대한 덜 민감한 방법으로 대상의 RGB 정보를 취득할 수 있는 방법을 사용하였다.

최근 디지털 비디오 데이터의 사용이 급격히 증가하면서 저급 수준의 정보를 이용하여 고급 수준의 내용 정보를 자동으로 추출하는 기술이 필요하게 되었다. 축구와 같은 분야에서는 그 중에서도 골, 프리킥, 파울 장면 등의 고급 수준 내용 정보가 중요한 의미를 갖게 되는데 특히, 이러한 장면 중 중요하다고 여기는 장면은 재연 장면을 통하여 다시 시청자에게 보여주게 되며, 축구 비디오에 대한 요약에서는 이런 장면들이 꼭 포함되어야 한다. 본 논문에서는 이러한 축구 비디오 데이터에서 재연 장면을 자동으로 추출하는 방법을 제안한다. 기본적으로는 축구 고유의 특징들을 이용하는데 첫 번째 특징은 샷의 길이가 너무 짧거나 너무 길지 않다는 것이고, 두 번째 특징은 재연 장면이라는 것은 장면이 느리게 다시 재생되는 것이기 때문에 움직임 특징이 일반적인 장면과는 다르다는 것이다. 본 논문에서는 오브젝트의 움직임을 구분하기 위하여 재연 장면을 두 가지 종류로 나누었다. 하나는 확대 상태의 재연 장면이고 다른 하나는 축소 상태의 재연 장면이다. 본 논문의 알고리즘을 적용하여 실험한 결과 Recall과 precision 모두 77% 이상 나오는 것을 알 수 있었다.

This paper presents a Soccer Game 3D Reencatment System which reenact the Important scene like getting a goal with image processing and computer graphics technologies. KBS Research Institute of Technology has developed the 3D Reenactment System of Soccer Game called ‘VPlay' to provide TV viewers with fresh images in soccer games. Vplay generates the reenactment of exciting and important soccer scenes by using computer graphics. Vplay extracts legion of players from video with color information, and then computes precise positions of players on the ground by using global motion estimation model and playground axis transformation model. The results are applied to locomotion generation module that generates the locomotion of virtual characters automatically. Using predefined motion and model library, Vplay reenacts the important scene in a quick and convenient manner Vplay was developed for live broadcasting of soccer games that demands rapid producing time and was used efficiently during past WorldCup and Asian Game.

The purpose of this study is to explore the teaching experience of first-time youth soccer leaders. To this end, four leaders registered in the U-12 team were selected from those with more than 10 years of player experience, less than 5 years of coaching experience, and a level C or higher of the Korea Football Association leader's license. Accordingly, the analysis categories and analysis units were categorized according to the research problem, and data analysis was conducted through an inductive method. As a result of the study, youth soccer leaders were starting their coaching with the mindset of "I shouldn't" and "I can do it" based on their past experiences. They who concerned their uncertainty about the future in the teaching field were struggling with how to communicate with student and were less professional in teaching and learning ability. but they were trying to gain expertise while feeling rewarded in teaching. Accordingly, it was discussed to improve the treatment of youth soccer leaders and improve the program that is the leader training system.

This study, based upon the Sturges' crisis stages, examines the crisis response communication strategies of Korea Professional Football League(KPFL) for the K-league match-fixing case as well as the frequency of related news articles and the source of information. To explore the crisis response communication strategies the Korea Professional Football League used, a total of 118 news articles were analyzed using the content analysis and frequency analysis. The unit of analysis for crisis response communication strategies is sentence. The frequency of news articles based upon the crisis stages shows highest rate at the acute crisis stage. The source of information for news reports shows that KPFL was one of the major sources of the news reports. KPFL's crisis response communication strategy throughout all stages of the crisis stage shows that corrective action strategy was used highest ratio. In particular, the crisis response communication strategy between team, player and KPFL was shown lack of consistency throughout all crisis stages. Implication and future research direction for the results are discussed.
