피부색 정보의 적응적 선택과 투영 기법을 이용한 얼굴 영역 추출 = Face Region Extraction Using Adaptive Selection of Skin Color Information and Projection

다국어 초록 (Multilingual Abstract)

In this paper, a face region extraction algorithm using adaptive selection of skin color information and projection is proposed. The face candidate region is extracted by using the proposed three-step processes according to the ratio between total pixels number and the extracted pixels number. After the extraction of face candidate image using adaptive skin color information, we project it into vertical direction to estimate the width of the face. Then the redundant parts of the face are efficiently removed by using the estimated face width. And the width information of the face is used at the horizontal projection step to extract the height of the face, and non-face regions such as the neck and some background regions, which are represented as the similar skin color, are effectively eliminated. From the experiment results for the various images, the proposed algorithm shows more accurate results than the conventional algorithm.
