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.
