Abstract

Abstract

This paper presents an approach to locate nose tip using the lower contour of the nose. Firstly we determine the candidate nose area through the prior knowledge of face and the location of two eyes. Then we extract the lower contour of the nose through calculating the confidence of the nose edges that detected by Canny operator. Finally, we use least square method to fit the lower contour into parabolic curve, and then locate the nose tip. The experiment results show that the proposed approach is accurate and practical.
