Abstract

Recently virtual advertising is located in an important area of interest in the TV market by convenience of application and reduction of cost. The methods of inserting a virtual advertising in broadcasting are Up-link that method insert the image through the production equipment of the broadcasting station and dispatch equipment and technical personnel in the shooting and Down-streaming that method insert a virtual image automatically in relay video using image processing technology. In recent years, the image processing technology is an important research area in the virtual advertising area for automatically insertion of advertising images. In this paper, we propose the method to extract less-informative region in sports video using image processing. The proposed method extracts less-Informative region through rectangle detection of Hough transform and analysis of color histogram distribution.

최근 가상광고는 비용의 절감 및 적용의 편의성으로 인하여 TV시장에서 중요한 관심 영역으로 자리 잡고 있다. 방송에 가상광고를 삽입하는 방법으로는 촬영현장에 장비와 기술진을 파견해 방송사의 제작 장비와 연동하여 이미지를 삽입하는 업링크(Uplink)기법과 영상처리 기법을 활용하여 중계 영상에 자동적으로 가상이미지를 삽입하는 다운스트리밍(Down streaming)기법이 있다. 최근에는 자동적인 가상광고 삽입을 위한 영상 처리 기술이 가상광고 영역에서 중요한 연구 분야로 자리 잡고 있다. 따라서 본 논문에서는 스포츠 영상 내에서 자동적으로 가상광고를 삽입하기 위해 영상처리 기법을 활용하여 저정보영역을 추출하는 방법을 제안한다. 제안 방법은 허프(Hough)변환을 이용한 사각형 검출과 검출된 사각형영역에 대한 색 히스토그램 분포의 분석을 통해 저정보영역을 추출한다.
