    Abstract

    It is difficult to get ideal facial contour using conventional edge extraction operator. In this paper, a new contour extraction method was presented. It was based on geometrical feature of human face. At first edges were extracted with the combination of SOBEL and CANNY operators. Redundant edges were removed consequently and useful edges were connected using facial geometrical feature. Satisfactory facial contour and good localization are achieved through this approach to meet the requirement for facial feature detection. Over 50 different face images are tested by this method and it is shown to produce results with high accuracy
