    文中介绍了一种用傅里叶变换来描述人眼图象轮廓和计算人眼几何参数的方法. 该方法将在复平面内的人眼轮廓分别做实轴和虚轴上的投影,然后对所得到的两种信号做傅里叶变换. 用经过傅里叶变换后得到的傅里叶系数既可以拟合出人眼的轮廓也可以计算人眼的几何参数. 其他方法相比,这种方法可以很好的分析那些轮廓相对平滑的图像,并且有很高的计算效率.

    This paper introduces a method to describe the contour of human eyes and calculate its geometric parameters.The method projects the eye contour placed in a complex plane into real axis and imaginary axis respectively and then make fourier transforms with the two signals.The fourier coefficients obtained by fourier transforms can be used to fit the eye contour or compute eye geometric parameters.Compared with other approaches,this method can make a good analysis of the images that have smooth boundary.In addition,it has higher computing efficiency.
