Facial Region Tracking in YCbCr Color Coordinates

YCbCr 컬러 영상 변환을 통한 얼굴 영역 자동 검출

In this study, the automatic face tracking algorithm is proposed by using the color and edge information of a color image. To reduce the effects of variations in the illumination conditions, an acquired CCD color image is first transformed into YCbCr color coordinates, and subsequently the morphological image processing operations, and the elliptical geometric measures are applied to extract the refined facial area.
