초록

언제 어디서나 사용하기 편리한 인터넷을 통해서 다양한 종류의 멀티미디어 콘텐츠가 자유롭게 유통되고 있는 반면, 어린이나 청소년에게 유해할 수 있는 영상 콘텐츠도 쉽게 얻을 수 있는 환경이 마련되어서 사회적으로 문제가 되고 있다. 본 논문에서는 인공 신경망을 이용하여 입력 영상의 유해성 유무를 자동으로 결정하는 방법을 제안한다. 본 논문에서 제안된 방법에서는 먼저 입력 영상으로부터 MCT 특징을 기반으로 사람의 얼굴 영역을 검출한다. 그런 다음, 색상 특징을 활용하여 피부 색상 영역을 찾고, 유두의 후보 영역들을 추출한다. 마지막으로 계층적인 인공 신경망을 활용하여 유두의 후보 영역들 중에서 실제적인 유두 영역만을 필터링함으로써 입력 영상의 유해성 유무를 확인한다. 본 논문의 실험결과에서는 인공 신경망을 이용한 제안된 방법이 입력되는 영상에서 유두 영역을 보다 강건하게 검출함으로써 영상의 유해 정도를 효과적으로 결정한다는 것을 보여준다.

Various types of multimedia contents have been widely spread and distributed with the Internet that is easy to use. Meanwhile, Multimedia contents can bright a social problem because juveniles can access such harmful contents easily through the Internet. This paper proposes a method to determine if an input image is harmful or not, using an neural network. The proposed method first detects a face region from an input image through MCT features. The method then extracts skin color regions using color features and obtains candidate nipple areas from the extracted skin regions. Subsequently, we determine if the input image is harmful, by filtering out non-nipple regions using the artificial neural network. Experimental results show that the proposed method can effectively determine the harmfulness of input images.
