| 摘 要： | 提出了一种基于鼻子下轮廓线的鼻尖定位算法.该算法首先利用人脸先验知识和眼睛位置确定鼻子候选区域,然后用Canny算子抽出鼻子边缘,通过计算其置信度获取鼻子下轮廓线,最后采用最小二乘法拟合鼻子下轮廓线为抛物线,从而确定鼻尖位置.实验表明,本算法具有较高的鼻尖定位精度和应用价值.

| 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. |
