基于内容的足球视频进球检索系统设计

Design of Soccer Video Goal Retrieval System based on Content

足球因其是世界第一大运动而拥有众多球迷。但是随着信息量的增长和生活节奏的加快,人们无暇观看整场足球比赛。进球是足球比赛中最精彩的部分,因此,分析足球视频并提取进球镜头集具有极大的现实意义。笔者设计了一个基于内容的足球视频进球检索系统,其基本功能包括基于记分牌的进球事件定位、基于自适应双阈值的镜头分割、基于球场颜色主色比率的镜头分类方、基于霍夫直线检测和主色比的球门检测。对不同视频进行检索的不同结果表明,进球事件的查准率可达100%。
