Abstract
문화콘텐츠기술(CT, Culture Technology)은 문화 산업 발전을 위한 기술로 문화콘텐츠 기획과 상품화, 미디어탑재, 전달의 가치사슬 과정 등 문화상품의 부가가치를 높이기 위해 소용되는 모든 형태의 유무형의 기술이다. 문화콘텐츠 기술(CT)분야에서 음악의 특징을 분석하여 다양한 어플리케이션을 개발하는 연구가 활발히 진행되고 있다. 이와 관련된 연구 중 EEG를 측정하고 그 결과에서 음악적 자극에 대한 반응을 검출하여 활용하는 연구가 주목받고 있다. 본 논문에서는 EEG에서 음악적 자극에 대응되는 반응신호들을 증폭시켜 평균화 하는 방법인 ERP(Event-Related Potentials) 실험을 기반으로 음색을 추출하는 과정에서 노이즈를 제거하기 위한 방법으로 ICA 알고리즘을 적용하여 음색 추출 및 노이즈 제거 결과에 따른 EEG의 특성을 분석하여 적용한다. Cultural Content Technology(CT, Culture Technology) for the development of cultural industry and the commercialization of technology, cultural contents, media, mount, pass the value chain process and increase the added value of cultural products that are good for all forms of intangible technology. In the field of Culture Technology, Music by analyzing the characteristics of the development of a variety of applications has been studied. Associated with EEG measures and the results of their research in response to musical stimuli are used to detect and study is getting attention. In this paper, the musical stimuli in EEG signals by amplifying the corresponding reaction to the averaging method, ERP (Event-Related Potentials) experiments based on the process of extracting sound methods for removing noise from the ICA algorithm to extract the tone and noise removal according to the results are applied to analyze the characteristics of EEG.
