Abstract: By analyzing the gray-scale characteristics of eyelashes and eyelids in normalized iris image, this paper presents a new eyelashes and eyelids detection method.This method can detect the eyelashes and eyelids simultaneously with a simple mathematical model.Firstly, proposed the image by median filter.Secondly, to minus the new image with original one.At last, figure out the skeleton of the image.Experimental results show that the method can detect eyelashs and eyelids quickly and effectively.Overcome the traditional methods for the eyelashes and eyelids to create different mathematical models which led to increase in complexity, shortcomings of testing slow.
