Abstract

The amount of UCCs (User Created Contents) has been increasing rapidly and is associated with a serious copyright problem. Automatic logo detection in videos is an efficient means of overcoming the copyright problem. However, logos have varying characteristics, which make logo detection and recognition very difficult. Especially, there are frequent logo transitions in a video, comprising several video contents. This disrupts accurate video segmentation based on logos. Therefore, this paper proposes an accurate logo transition detection method for recognizing logos in digital video contents. The proposed method accurately segments a video according to logo and efficiently recognizes various types of logos. The experimental results demonstrate the effectiveness of the proposed method for logo detection and video segmentation according to logo.

UCC(User Created Contents)의 급격한 증가에 따라 저작권 문제도 크게 대두되고 있다. 자동 로고 인식은 이러한 저작권 문제를 해결하기 위한 효율적인 방법이다. 로고는 다양한 특징을 가지고 있고, 이러한 특징들은 로고 검출과 인식을 어렵게 한다. 특히, 비디오 내에 빈번한 로고 전이가 일어날 경우, 정확한 로고 인식과 로고 기반 분할이 어렵다. 따라서 본 논문에서는 디지털 비디오에서 로고 인식을 위한 정확한 전이 검출 방법과 다양한 로고 타입 인식 방법을 제안한다. 제안한 로고 검출과 로고에 따른 비디오 분할을 이용하여 다양한 비디오에 대한 좋은 실험 결과를 얻을 수 있었다.
